Heating  and  Ventilation  for  Factories 

A  HEATING  SYSTEM  which  also  ventilates  your  factory  will  bring  you  the  greatest  returns. 
The  Sturtevant  System  provides  fresh  outdoor  air  which  is  heated  and  then  forced  by  a 
fan  to  every  corner  of  the  building.  Good  ventilation  so  abundantly  supplied  means  increased  output 
to  you  and  health  to  your  employees.  Direct  radiation  systems  either  provide  no  ventilation 
at  all  or  are  used  in  connection  with  separate  ventilation  systems  dependent  upon  weather  and 
atmospheric  conditions.  The  Sturtevant  System  is  always  positive  in  action  and  independent  of  the 
weather.  In  this  indirect  system  only  one-fifth  to  one-third  as  much  heating  surface  is  needed  as 
in  direct  radiation  systems. 

All  the  heating  surface  of  the  Sturtevant  apparatus  is  centralized  in  a  single  unit  and  contained 
in  a  fire-proof  jacket.  There  is  no  chance  of  frozen  pipes  or  of  racketing  water-hammer  throughout 
the  building.  One  operating  engineer  has  the  control  of  the  entire  system. 

The  Sturtevant  System  will  heat  your  factory  the  quickest  on  a  winter's  morning.  In  summer 
it  will  cool  your  shop  and  supply  abundant  air  for  your  workmen. 

You  can  get  Sturtevant  quality  only  by  using  Sturtevant  apparatus.  The  difference  in  price  is 
a  difference  in  quality.

Midvale  Steel  Co.,  Nicetown,  Pa. 

THE  duct  system  used  for  heating  the  Ordnance  Machine  Shop  No.  4  of  the  Midvale  Steel  Co. 
of  Nicetown,  Pa.,  is  very  simple  and  efficient.     A  galvanized  iron  duct  that  shows  very  plainly 
in  the  photograph  is  carried  entirely  around  the  inside  walls  of  the  building,  delivering  air  at  intervals 
through  short  spouts  directed  downward  and  toward  the  centre  of  the  shop.     The  part  of  the  shop 
near  the  walls — naturally  the  coldest — is  thus  well  heated. 

The  machine  shop  has  a  content  of  about  5,250,000  cubic  feet.  The  four  apparatuses  heat  this 
to  a  temperature  of  65  degrees  in  zero  weather  with  a  thirty-minute  air  change.  The  building  is 
heated  on  a  recirculation  basis.  Steam  at  from  2  to  5  pounds  is  used  in  the  heaters. 

Each  of  the  four  apparatuses  has  an  8  by  4  foot  fan  in  a  three-quarter  steel  plate  housing,  up-blast 
discharge.  Each  fan  is  direct  connected  to  a  Sturtevant  8  by  12  steam-engine.  The  heaters  con- 
tain 2,510  square  feet  of  radiating  surface  each,  and  are  built  on  ten  four-row,  five-foot  heater  bases,  and 
jacketed  in  the  usual  manner  so  that  the  air  is  drawn  through  the  heater. 

The  four  apparatuses  are  set  in  the  corners  of  the  building  on  the  floor,  and  discharge  into  the 
galvanized  duct  above.

Heating  and  Humidifying  in  Textile  Mills 

\  V  7HERE  buildings  are  of  open  construction,  such  as  textile  mills  where  every  floor  is  practically 
yy  one  room,  the  standpipe  method  of  distribution  is  often  used.  The  drawing  on  the  opposite  page 
illustrates  this  method  plainly.  In  this  particular  installation,  in  the  weave  shed  of  the  Burgess  Mills, 
Pawtucket,  R.I.,  there  is  only  one  floor  to  be  heated,  but  in  buildings  of  several  stories  a  similar  arrange- 
ment is  applicable. 

The  fan,  located  in  the  basement  and  drawing  air  from  the  heater,  discharges  it  vertically  upward 
into  a  short  flue  or  standpipe  which  extends  into  the  room  above.  At  a  height  of  about  ten  feet  from  the 
floor  the  air  is  distributed  horizontally  in  all  directions  through  short  pipes  as  shown  in  the  drawing. 
Located  in  the  centre  of  a  space  to  be  heated,  this  system  minimizes  the  cost  of  installation,  as  considerable 
galvanized  iron  piping  and  special  duct  construction,  necessary  in  other  arrangements,  are  eliminated. 

It  is  essential  for  the  highest  economy  in  textile  mills  that  the  air  shall  be  moist.  It  is  well  known 
that  the  effect  of  dry  air  is  to  cause  a  change  of  several  numbers  in  the  yarn  and  as  much  as  three  per 
cent,  in  weight,  weakening  the  yarn  and  causing  it  to  snap  and  break,  while  the  quality  and  width  of 
woven  goods  is  noticeably  affected.  With  a  moist  atmosphere  these  difficulties  are  not  encountered. 

Owing  to  the  fact  that  with  the  Sturtevant  system  air  may  be  moistened,  the  condition  of  the 
atmosphere  in  a  mill  is  always  the  same  and  may  be  controlled  without  regard  to  external  conditions. 
The  percentage  of  moisture  in  the  air  can  be  closely  regulated  to  obtain  the  most  economical  operation 
of  the  mill  and  the  most  comfortable  working  conditions.

Burgess  Mills,  Pawtucket,  R.I. 

THE  Burgess  Mills  consist  of  two  main  buildings:   the  spinning  mill  which  is  three  stories  in  height, 
and  the  weave  shed  which  is  a  single  story.     The  spinning  mill  is  467  by  101  feet  and  has  a  total 
content  of  about  2,240,000  cubic  feet.     The  weave  shed  is  318  feet  long  by  250  feet  wide  and  has  a  total 
content,  exclusive  of  the  basement,  of  1,431,000  cubic  feet. 

The  apparatus  heating  the  spinning  mill  consists  of  an  11  by  5^  foot  fan  wheel  in  a  three-quarter 
housing,  driven  direct  connected  by  a  10  by  12  Sturtevant  horizontal  steam  engine.  The  heater  con- 
tains 5,100  square  feet  of  heating  surface  built  in  a  double  group  on  12  four-row  mitre  type  sections, 
jacketed  so  that  air  is  drawn  through  by  the  fan.  The  outside  section  of  each  group  receives  the  exhaust 
steam  from  the  engine  while  the  other  coils  are  heated  with  hot  water  which  is  circulated  by  means  of  a 
centrifugal  pump.  The  fan  discharges  air  into  a  duct  in  the  basement,  which  runs  the  length  of  the 
building  and  from  which  flues,  concealed  in  the  wall  of  the  mill,  carry  the  air  to  the  various  floors. 

There  are  two  apparatuses  heating  the  weave  shed.  These  are  located  in  the  basement  and  deliver 
air  through  standpipes  as  described  on  a  previous  page.  The  fans  are  6  by  3^  foot  wheels  in  three- 
quarter  steel  plate  housings  and  are  driven  by  direct  connected  Sturtevant  6  by  9  horizontal  steam 
engines.  The  heaters  are  built  on  six  four-row  mitre  sections  containing  1,875  square  feet  each.  The 
outside  section  of  each  heater  receives  exhaust  steam  from  the  engine  while  hot  water  is  circulated 
through  the  rest  of  the  coils.

United  States  Navy  Yard,  Brooklyn,  N.Y. 

TWO  of  the  four  apparatuses  heating  the  machine  shops  at  the  United  States  Navy  Yard  at  Brooklyn, 
N.Y.,  are  shown  on  the  opposite  page.     These  apparatuses,  as  can  be  seen  in  the  illustrations,  are 
mounted  upon  special  platforms  hung  from  the  roof  trusses  of  the  building.    The  air  ducts  are  run  through 
the  trusses,  distributing  the  heated  air  to  every  corner  of  the  shop.     Such  an  arrangement  as  this  shows 
how  the  Sturtevant  apparatus  may  be  placed  out  of  the  way. 

The  fans  used  in  these  apparatuses  are  of  special  construction.  Three  4^-foot  blast  wheels,  each  in 
a  special  housing  with  a  top  horizontal  discharge,  are  mounted  on  the  same  shaft.  The  fans  are  driven 
by  direct  connected  alternating  current  motors.  The  heaters  contain  2,510  square  feet  of  heating  sur- 
face each,  built  on  5  by  6  foot  sections,  and  arranged  in  a  special  heater  jacket  so  that  the  air  is 
blown  through  the  heater. 

In  a  factory  installation  such  as  this  the  space  per  person  is  so  large  that  the  need  of  ventilation  is 
not  so  important  as  in  a  mill  where  hundreds  are  working  in  the  same  room.  Therefore,  a  great  saving 
of  heat  may  be  effected  by  the  recirculation  of  the  air  of  the  shop  through  the  heating  system.

Lorain  Steel  Co.,  Johnstown,  Pa. 

THE  plan  of  the  Bending  and  Cold  Saw  building  of  the  Lorain  Steel  Co.  which  is  shown  here  indicates 
the  position  of  the  heating  apparatus  and  the  arrangement  of  the  hot-air  flues.     The  apparatus  is 
centrally  located  at  one  end  of  the  shop,  discharging  air  into  a  duct  system  above,  which  divides  into 
two  branches,  as  is  indicated  on  the  plan  of  the  shop. 

This  system  illustrates  how  a  certain  class  of  one-story  buildings  may  be  heated  by  a  very  simple 
duct  system.  Although,  as  the  illustration  shows,  there  are  two  roofs  to  this  building,  the  interior  is 
practically  one  room.  The  galvanized  iron  heating  ducts  are  carried  by  the  roof  trusses  of  the  build- 
ing, discharging  the  hot  air  into  the  shop  through  short  spouts. 


The  fan  is  a  9j/£  by  4^  foot  blast  wheel  in  a  three-quarter  steel  plate  housing  with  an  up-blast  dis- 
charge.    The  fan  is  driven  by  a  direct  connected  9  by  12  Sturtevant  horizontal  steam-engine. 

The  heater  contains  4,254  square  feet  of  heating  surface,  built  on  twelve  four-row,  six-foot  heater 
bases,  and  set  in  a  double  group,  jacketed  so  that  the  air  is  drawn  through  the  heater  by  the  fan.

THE  illustration  opposite  shows  very  plainly  the  construction  of  the  Sturtevant  standard  heater. 
This  particular  heater  is  in  the  Storage  Building  of  the  Pierce  Arrow  Motor  Car  Co.  at  Buffalo, 
N.Y.     It  consists  of  4,818  square  feet  of  heating  surface,  and  is  arranged  in  a  double  group. 

The  pipe  used  in  Sturtevant  heaters  is  especially  made  for  us  of  extra  weight,  so  as  to  make  it  possible 
to  use  a  full  thread  on  the  joints  without  sacrificing  strength.  These  pipes  are  screwed  into  sectional 
heater  bases  of  cast  iron,  built  for  two  or  four  rows  of  staggered  pipes.  Steam  enters  one  end  of  the  heater 
base  from  the  steam  header,  passes  up  through  the  pipes  on  one  side  and  down  on  the  other,  where  the 
water  of  condensation  is  drawn  off  through  the  header  on  the  end.  The  bases  and  headers  are  divided 
to  provide  an  entrance  and  exit  for  the  steam.  The  heater  is  drained  through  steam-traps. 

When  the  fan  is  driven  by  a  steam-engine,  the  exhaust  steam  is  used  in  the  heater,  thus  eliminating 
the  cost  of  running  the  engine. 

Apparatus  in  another  of  the  buildings  of  this  plant  heats  2,700,000  cubic  feet  of  space.  The  fan 
used  is  a  number  20  Sturtevant  Multivane  exhauster  in  a  seven-eighths  steel  plate  housing.  The  fan  is 
driven  by  a  direct  connected  Sturtevant  1  \]/2  by  16  horizontal  steam-engine.  The  heater  contains  8,064 
square  feet  of  heating  surface,  and  is  built  in  three  groups.  This  heater  will  maintain  a  temperature 
of  70  degrees  throughout  the  building  with  the  thermometer  at  20  degrees  below  zero.

New  York  Shipbuilding  Co.,  Camden,  N.J. 

THE  machine  shop  of  the  New  York  Shipbuilding  Co.  of  Camden,  N.J.,  is  built  with  a  two-story 
gallery  on  either  side,  as  shown  in  the  photograph.     The  method  employed  in  the  heating  of  such 
a  building  is  to  throw  air  into  the  galleries  on  both  sides  and  allow  it  to  diffuse  throughout  the  rest 
of  the  building. 

The  position  of  the  ducts  is  very  plainly  shown.  Four  galvanized  iron  ducts  run  lengthwise 
of  the  building  and  are  supplied  with  hot  air  from  fans  and  heaters  situated  on  raised  platforms  half- 
way between  the  first  and  second  floors.  These  ducts  discharge  downward  to  the  lower  floor  and 
upward  to  the  upper  floor. 

Four  sets  of  apparatus  are  used  for  the  heating  of  this  building,  two  being  placed  each  side  of  the 
shop.  The  fans  are  special  8^  by  4  foot  blast  wheels  in  full  steel  housings,  three-quarters  above  the 
platform  floor.  Each  fan  is  driven  direct  connected  by  a  Sturtevant  8  by  12  steam-engine,  receiving 
steam  at  80  pounds.  Each  of  the  heaters  has  an  actual  capacity  of  2,5 10  square  feet  of  heating  surface, 
built  on  ten  four-row,  five-foot  sections,  six  feet  high.  Each  heater  is  jacketed  in  a  special  steel  plate 
heater  jacket,  and  so  arranged  that  the  air  is  drawn  through  the  heater.

Heating  and  Ventilation  in  Railroad  Work 

THE  Sturtevant  system  has  always  been  the  standard  for  railroad  work.     It  fills  the  demand  for 
an  economical  system  that  is  reliable,  efficient,  and  durable.     The  following  pages  show  a  few 
of  the  variety  of  applications  of  the  Sturtevant  system  to  railroad  work. 

For  the  heating  of  roundhouses  the  Sturtevant  system  is  particularly  valuable.  Although  we 
mention  but  two  roundhouses  in  this  book,  practically  every  railroad  in  the  United  States  and  Canada 
uses  this  system  in  its  roundhouses. 

In  paint  shops  the  drying  effect  of  the  hot-blast  system  gives  it  precedence  over  other  systems 
of  heating.  The  saving  in  time  alone,  due  to  the  abundant  supply  of  warm  dry  air,  would  recom- 
mend it  in  preference  to  other  systems. 

In  railroad  shops,  where  all  processes  and  apparatus  must  be  of  the  most  efficient,  the  Sturtevant 
system  is  universally  used.  The  heating  of  large  car  and  erecting  shops  can  be  done  the  most  eco- 
nomically by  this  hot-blast  system.  Only  from  one-third  to  one-fifth  as  much  radiating  surface 
is  required  as  with  the  ordinary  direct  radiation  system. 

Sturtevant  apparatus  has  the  approval  of  railroads  and  car  builders  because  with  Sturtevant 
apparatus  they  are  assured  Sturtevant  quality.

Louisville  &  Nashville  Railroad,  South  Louisville,  Ky. 

THE  Louisville  &  Nashville  Railroad  Company  control  and  operate  over  seven  thousand  miles 
of  track  in  a  territory  extending  from  Ohio  to  the  Gulf  of  Mexico.  The  railroad  shops  of  this  com- 
pany located  at  South  Louisville  are  heated  by  Sturtevant  apparatus  in  connection  with  the  Webster 
Vacuum  System. 

The  iron  and  brass  foundry  is  heated  by  two  sets  of  Sturtevant  apparatus,  one  set  consisting  of  a 
6  by  9  foot  steel  plate  fan,  belt  driven  by  a  Sturtevant  MP-4  motor.  The  heater  contains  1 ,418  square 
feet  of  heating  surface,  and  is  jacketed  in  connection  with  the  fan  which  draws  the  air  through  the  heater. 
The  other  fan  is  a  7  by  10^  foot  steel  plate  exhauster,  motor  driven.  The  heater  contains  1,606  square 
feet  of  heating  surface. 

It  will  be  noticed  that  this  fan  is  provided  with  a  special  steel  plate  housing  with  a  double  discharge. 
The  picture  shows  how  the  air  is  distributed  from  the  main  duct  by  a  series  of  galvanized  steel  pipes  which 
discharge  into  the  main  room  and  under  the  gallery.  A  similar  apparatus  heats  the  other  end  of  the 
building. 

This  building  contains  about  1 ,762,000  cubic  feet,  and  the  apparatus  installed  maintains  a  temperature 
of  55  degrees  in  the  severest  weather.  In  summer  the  apparatus  provides  a  system  of  forced  ventila- 
tion. The  apparatus  is  so  arranged  that  the  air  may  either  be  recirculated  or  so  that  fresh  air  may  be  used. 

The  apparatus  in  the  Boiler  Erecting  and  Machine  Shop  is  so  arranged  that  there  are  two  fans  in  each 
end  of  the  building,  making  four  sets  in  all.  These  are  9J^  by  4J/2  foot  steel  plate  exhausters  in  three- 
quarter  steel  plate  housings,  driven  direct  connected  by  9  by  12  horizontal  Sturtevant  steam-engines. 
The  heaters  contain  2,647  square  feet  each,  and  are  jacketed  for  the  air  to  be  drawn  through. 


Interior  of  the  Iron  and  Brass  Foundry  of  the  Louisville  &  Nashville  Railroad  Co. 


The  apparatus  of  the  General  Stores  Building  is  arranged  to  meet  varying  requirements  of  service. 
The  third  floor  of  this  building  is  occupied  by  offices,  the  first  two  by  storerooms.  In  winter  the  offices 
are  partly  heated  by  direct  radiation,  being  supplemented  by  the  Sturtevant  hot-blast  system,  which 
heats  the  storage  rooms  and  which  provides  a  twenty-minute  change  of  air  in  the  offices.  In  summer 
all  the  air  from  the  fan  is  used  to  ventilate  the  offices,  after  it  has  been  cleaned  and  cooled  by  an  air 
washer.  The  fan  is  a  5J^  by  8J4  foot  steel  plate  exhauster,  belted  to  a  Sturtevant  motor.  The 
heater  contains  880  square  feet  of  heating  surface. 

The  air  for  heating  the  paint  and  tender  shops  is  drawn  through  an  air  washer  to  remove  dust 
and  dirt.  Special  care  was  taken  to  provide  large  air  ducts  in  the  paint  shop,  so  that  the  entering  air 
would  not  stir  up  dust.  The  use  of  a  blower  system  in  a  paint  shop  increases  the  rapidity  with  which  the 
paint  and  varnish  dry. 

The  problem  of  supplying  heated  air  for  ventilation  and  heating  purposes  in  the  planing  mill  is  one 
requiring  special  attention,  as  in  such  buildings  more  air  must  be  supplied  than  is  exhausted  by  the  plan- 
ing mill  exhausters,  so  that  there  may  be  no  inward  drafts  and  so  that  an  equable  temperature  may  be 
maintained. 

The  planing  mill  contains  about  920,000  cubic  feet  and  is  provided  with  two  sets  of  apparatus.  The 
fans  are  5}/£  by  8J4  foot  steel  plate  blowers  with  bottom  horizontal  discharge  and  with  special  casings. 


These  fans  are  driven  direct  connected  by  5  by  ll/%  Sturtevant  steam  fan  engine.  Each  heater 
contains  2,264  square  feet  of  radiating  surface,  built  on  eight  four-row  and  two  two-row,  five-foot  sections. 
Each  heater  is  arranged  in  a  double  group,  and  jacketed  so  that  the  air  is  blown  through  the  heater  by 
the  fan.

Heating  of  Railroad  Roundhouses 

FOR  heating  roundhouses  the  Sturtevant  system  is  especially  efficient.      The  abundance  of  warm 
air  supplied  directly  to  the  engine  pits  melts  the  accumulation  of   ice   and   snow  which  gathers 
on  the  running  gear  of  locomotives  and  carries  away  the  moisture.     This  drying  action  is  possible 
because  of  the  positive  circulation  of  warm  dry  air  through  the  building. 

The  installation  at  the  Terminal  Railroad  Association  roundhouse  at  East  St.  Louis  is  representa- 
tive of  the  arrangement  generally  adhered  to  in  the  heating  of  roundhouses  by  the  Sturtevant  system. 
On  the  opposite  page  is  shown  a  plan  of  this  particular  roundhouse  with  the  heating  ducts  indicated. 
The  fan  blows  directly  into  an  underground  concrete  duct,  which  follows  the  contour  of  the  building 
and  from  which  tile  ducts  convey  the  air  to  the  engine  pits. 

On  the  following  pages  are  illustrations  of  the  fifty-eight-stall  roundhouse  of  the  Chicago  & 
Northwestern  Railway  Co.,  Fulton,  111.  This  is  the  largest  roundhouse  in  the  world,  built  in  the  form 
of  a  complete  circle  and  with  a  diameter  of  483  feet. 

The  fans  for  this  heating  system  are  two  13-foot  steel  plate  exhausters.  The  heaters  contain 
6,979  square  feet  of  heating  surface.

New  York,  Ontario  &  Western  Railroad, 
Middletown,  N.Y. 

THE  paint  shop  of  the  New  York,  Ontario  &  Western  Railroad  at  Middletown,  N.Y.,  is  about 
320  by  67  feet,  and  contains  three  tracks  running  nearly  its  entire  length.  At  one  end  there  are 
several  small  rooms  for  upholstering,  wash-rooms,  and  offices.  The  total  content  of  the  building  is 
826,672  cubic  feet,  and  the  heating  apparatus  provides  an  eighteen-minute  change  of  air. 

The  apparatus  is  located  in  a  small  building  adjoining  the  main  shop.  The  fan  discharges  into 
an  underground  concrete  duct,  which  leads  directly  across  the  centre  of  the  building.  At  right  angles 
on  either  side  four  tile  ducts  run  the  length  of  the  building,  with  Y  branches  at  frequent  intervals  into 
which  galvanized  risers  are  fastened.  These  risers  project  a  slight  way  above  the  floor  of  the  shop, 
discharging  the  heated  air  into  the  shop  as  is  shown  in  the  illustration. 

The  apparatus  consists  of  an  8  by  4  foot  steel  plate  exhauster  in  a  three-quarter  steel  plate 
housing  with  a  bottom  horizontal  discharge.  This  fan  is  driven  direct  connected  by  an  8  by  12 
horizontal  side  crank  engine.  The  heater  contains  2,510  square  feet  of  heating  surface,  built  on  ten 
four-row,  five-foot  sections.  The  heater  is  jacketed  in  a  double  group  in  such  a  way  that  air  is  drawn 
through  it  by  the  fan. 

The  necessity  of  an  efficient  heating  system  in  a  paint  shop  is  evident.  The  drying  action  of  the 
hot  air  facilitates  the  work  and  cuts  down  very  materially  the  time  necessary  to  dry  painted  cars.

Osgood  Bradley  Car  Co.,  Worcester,  Mass. 

REPRODUCED  here  is  a  drawing  of  part  of  the  Forge  and  Truck  Shop,  the  Erecting  Shop,  the 
Planing  Mill,  and  the  Cabinet  Shop  of  the  Osgood  Bradley  Car  Co.,  which  are  heated  by  three 
apparatuses  of  Sturtevant  make.  The  building  averages  a  length  of  490  feet  and  a  width  of  295  feet 
with  an  extreme  clean  height  of  40  feet. 

The  apparatuses  consist  of  fan,  engine,  and  two  heaters  each,  and  are  located  in  specially  constructed 
fan  houses  adjoining  the  building.  The  air  for  heating  is  recirculated  from  the  shops. 

Two  warm-air  ducts  run  the  entire  length  of  the  building  just  below  the  roof  trusses,  and  are  sup- 
plied with  air  from  the  fans  by  cross  ducts.  A  branch  pipe  leads  from  the  main  duct  downward  along 
each  of  the  steel  columns  supporting  the  roof,  and  discharges  into  the  shops. 

Apparatus  No.  1  is  arranged  so  as  to  handle  the  heating  of  the  Cabinet  Shop,  one-half  of  the  Planing 
Mill,  and  one-quarter  of  the  Erecting  Shop,  and  consists  of  a  No.  16  Sturtevant  Multivane  fan  with  a 
capacity  of  70,000  cubic  feet  per  minute  at  160  revolutions  per  minute.  This  is  direct  connected  to  a 
10  by  12  Sturtevant  steam-engine.  The  two  heaters  contain  1,504  square  feet  of  heating  surface,  built 
on  four-row  six-foot  bases. 

Apparatus  No.  2  is  practically  a  duplicate  of  apparatus  No.  1 ,  heating  one-half  of  the  Planing  Mill 
and  one-quarter  of  the  Erection  Shops,  about  1 ,400,000  cubic  feet  of  space.  Drawing  on  opposite  page 
shows  apparatus  No.  2. 

Apparatus  No.  3  heats  about  2,000,000  cubic  feet  in  the  Truck  and  Erection  Shops.  The  fan  is  a 
No.  18  Sturtevant  Multivane,  capable  of  100,000  cubic  feet  of  air  per  minute  at  149  revolutions  per 
minute.  Heaters  are  in  two  groups,  containing  2,008  square  feet  of  heating  surface,  built  on  eight  four- 
row,  five-foot  bases. 

Buildings  of  more  recent  construction  are  also  heated  by  the  Sturtevant  system.

G.  C.  Kuhlman  Car  Co.,  Collingwood,  Ohio 

THE  photograph  on  the  opposite  page  shows  one  of  the  apparatuses  heating  the  Finishing  and  Erect- 
ing Shops  of  the  G.  C.  Kuhlman  Car  Co.     It  will  be  noticed  that  the  fan  has  a  double  discharge,  sup- 
plying two  systems  of  heating  ducts.     Placed  in  the  roof  this  way,  the  heating  apparatus  takes  up  no 
otherwise  valuable  room. 

The  system  of  ducts  and  discharge  pipes  is  clearly  shown  by  the  photograph.  The  ducts  lead  along 
the  walls  of  the  building,  discharge  pipes  leaving  them  vertically  and  following  down  the  wall  to  where 
they  discharge  into  the  shop  through  outlets  equipped  with  hand-operated  dampers. 

There  are  two  sets  of  apparatus  heating  this  shop.  The  fan  of  each  set  is  an  8  by  4  foot  blast 
wheel  in  a  special  three-quarter  steel  plate  housing  with  a  double  discharge  and  a  special  lower  quarter 
housing.  The  fans  are  driven  by  direct  connected  8  by  12  Sturtevant  horizontal  steam-engines.  The 
heaters  contain  2,570  square  feet  of  heating  surface  each,  built  on  eight  four-row  and  two  two-row 
heater  bases. 

The  apparatus  for  the  Machine  Shop,  Forge  Shop,  and  Storage  Room  is  shown  on  the  following  page. 
The  fan  is  a  6  by  3^2  f°ot  blast  wheel  in  a  three-quarter  steel  plate  housing  with  a  special  double  dis- 
charge. The  fan  is  driven  by  a  direct  connected  Sturtevant  horizontal  side  crank  engine.  The  heater 
contains  1 ,748  square  feet  of  heating  surface.

Necessity  of  Ventilation 


air  we  breathe  is  the  life-giver.     Taken  into  the  lungs,  the  oxygen  it  contains  is  carried  by 

the  blood  to  all  parts  of  the  body  where  the  combustion  of  the  organic  tissues  takes  place.  The 
carbonic  acid  gas  formed  by  this  process  is  returned  to  the  lungs  and  there  exhaled.  If  this  supply 
of  air  entering  the  lungs  is  impure,  poisonous  or  insufficient,  the  vital  functions  are  hindered,  inter- 
rupted or  discontinued  as  the  case  may  be,  and  the  consequence  is  physical  discomfort,  illness  or,  in 
extreme  cases,  death. 

The  conditions  influencing  the  relation  of  air  to  health  have  been  carefully  studied.  Data  has 
been  accumulated  by  investigators,  and  experiments  have  proved  the  necessity  of  proper  ventilation 
in  all  rooms  occupied  by  one  or  more  persons.  The  question  is  one  of  such  great  urgency  that  active 
legislation  in  many  states  and  most  cities  has  prescribed  laws  with  regard  to  ventilation. 

There  is  no  place  where  the  evil  effects  of  poor  ventilation  are  so  readily  noticed  or  the  results 
so  far-reaching  as  in  the  modern  school-house.  During  his  early  years  the  child  is  easily  attacked  by 
pneumonia,  catarrh,  consumption  and  other  throat  and  lung  diseases  that  are  so  readily  infectious 
in  a  room  poorly  ventilated.  While  not  always  evident  in  youth,  afflictions  often  come  in  later  life 
that  are  caused  by  the  undermining  of  health  during  school-days,  the  time  when  both  mind  and  body 
should  have  been  strengthened  the  most. 

The  most  perfect  system  of  ventilation  is  none  too  good  for  the  school-house.  The  extra  expense 
of  the  best  ventilation  system  is  more  than  warranted  by  the  saving  in  physicians'  fees  and  freedom 
from  illness.

Methods  of  Ventilation 


TWO  general  methods  of  ventilation  present  themselves,  natural  and  mechanical.  With  the  natural 
method  a  flue  or  chimney  is  utilized  to  produce  the  draft  necessary.  To  aid  the  draft,  steam 
coils  or  gas  jets  are  often  placed  at  the  bases  of  these  flues,  heating  the  air  and  causing  it  to  move 
rapidly  up  the  flue.  Through  vents,  opening  into  these  flues  from  the  rooms,  the  air  is  drawn  and  ex- 
pelled at  the  top  of  the  flue. 

The  mechanical  method  provides  a  fan  which  forces  air  into  or  out  of  a  room  through  a  system  of 
ducts  and  flues,  providing  a  constant  change  of  air  within  the  room.  The  advantages  of  mechanical 
over  the  natural  methods  are  evident.  In  the  case  of  steam-heated  flues  the  heat  is  mostly  wasted, 
as  it  serves  no  useful  purpose  other  than  that  of  moving  the  air  in  the  flues.  The  greater  efficiency 
of  the  fan  compared  with  a  heated  flue  precludes  all  argument  on  grounds  of  economy  as,  even  under 
conditions  most  disadvantageous  to  the  fan,  it  still  maintains  a  considerable  advantage  over  the  heated 
flue  in  point  of  heat  economy.  This  economy  is  shown  by  the  decreased  coal  bill. 

The  photographs  in  this  book  show  a  few  of  the  many  well  known  school  buildings  in  which 
Sturtevant  apparatus  is  installed. 


Mechanical  Ventilation 


THE  combination  of  heating  and  ventilation  by  means  of  a  fan,  steam  heater  and  system  of  dis- 
tributing piping  was  first  applied  by  the  B.  F.  Sturtevant  Company  more  than  fifty  years  ago, 
and   is   therefore   rightly    known   as   the   Sturtevant  System.      The    System   as    generally    applied, 
provides  for  the  forcing  of  warmed  air  into  the  rooms  to  be  heated  and  ventilated,  the  air  performing

the  duty  of  ventilation  and  providing  the  means  of  conveying  heat.  The  warming,  especially  in  cold 
weather,  is  necessary  to  guard  against  cold  drafts  and  does  not  affect  the  quality  of  the  air.  Thus  by 
one  apparatus  are  provided  heating  and  ventilation. 

The  heater  in  the  Sturtevant  System  is  located  so  that  the  fan  either  draws  or  blows  air  through 
the  heater  or  a  combination  of  both.  The  construction  of  these  heaters  is  described  elsewhere.  An 
air  washer,  which  cleanses  the  air  of  dust  and  impurities,  is  also  placed  between  the  fan  and  the  first 
heating  coil,  so  that  all  the  air  delivered  to  the  school-rooms  is  fresh  and  washed.  The  first  heater 
or  tempering  coil,  as  it  is  called,  slightly  warms  the  air  before  it  enters  the  washer,  the  second  heats 
the  air  to  be  delivered  to  the  school-rooms. 

Around  this  second  heater  there  is  usually  provided  a  by-pass  through  which  part  of  the  air  is 
forced,  the  fan  thus  delivering  both  hot  and  tempered  air  into  a  divided  plenum  chamber,  or  double 
duct.  The  supply  of  air  to  the  various  rooms  is  taken  from  both  hot  and  tempered  air  chambers  and 
in  such  proportions  that  the  final  temperature  of  the  mixture  and  hence  the  temperature  of  the 
room  can  be  regulated  as  desired.  Thus,  without  affecting  the  volume  of  air  entering  the  room,  the 
temperature  may  be  carefully  controlled.  Thermostatically  operated  mixing  dampers  ensure  a  constant 
temperature  in  every  room,  controlled  independently  in  every  room. 

Distribution  to  the  rooms  is  accomplished  by  means  of  ducts  and  flues  as  indicated  in  the  various 
drawings  throughout  this  book.  Registers  are  placed  in  the  walls  about  eight  feet  from  the  floor, 
while  vent  registers,  opening  into  vent  flues  that  carry  the  vitiated  air  from  the  room  to  the  outer  air, 
are  also  placed  in  the  walls  near  the  floor.  An  exhaust  fan,  connected  to  the  vent  flues,  aids  in  ridding 
the  rooms  of  foul  air  but  is  not  used  except  when  the  building  is  large  enough  or  the  system  com- 
plicated enough  to  require  it.

A  Typical  Installation 


ATYPICAL  installation  of  the  Sturtevant  System  in  a  school  building  is  shown  in  the  drawing 
on  the  opposite  page.  This  is  a  section  of  a  building  with  the  heating  and  ventilating  ducts 
clearly  shown  and  the  path  of  the  air  indicated  by  arrows. 

The  air  enters  the  building  from  the  outside  through  screened  openings  that  are  situated  in  the 
basement,  hidden  in  the  drawing  by  the  tempering  coils,  and  then  passes  through  two  tempering  coils 
and  through  a  by-pass  which  is  located  between  the  coils.  The  by-pass  damper  is  operated  by  a 
pneumatic  diaphragm  and  controlled  by  the  temperature  of  the  building  by  means  of  a  thermostat. 
The  air  is  drawn  into  the  fan  and  blown  through  a  second  heater  and  through  a  by-pass  below 
this  heater  into  a  double  duct  which  is  constructed  of  concrete  and  laid  below  the  basement  floor. 
The  duct  is  shown  in  outline  on  the  previous  page. 

Air  from  this  double  duct  enters  flues  which  are  located  in  the  walls  of  the  building  and  rises 
in  them,  entering  the  various  rooms  through  registers  placed  in  the  walls  about  8  feet  above  the  floor. 
These  are  shown  in  the  sectional  view  opposite.  The  vitiated  air  leaves  the  room  through  registers 
opening  into  the  vent  flues  which  carry  the  air  to  the  attic,  where  it  is  allowed  to  escape  to  the 
atmosphere  through  ventilators. 

The  double  duct  contains  heated  air  above  and  tempered  air  below.  The  temperature  of  the 
air  entering  the  room  is  regulated  by  automatically  mixing  varying  quantities  of  heated  and  tempered 
air  at  the  base  of  the  flue.  As  previously  explained,  this  mixing  is  accomplished  by  means  of  mixing 
dampers  controlled  by  pneumatic  diaphragms  that  are  regulated  by  thermostats  placed  in  the  rooms 
themselves.

Hot  Blast  Heating 


IT  is  universally  conceded  that  no  school  building  should  be  erected  without  a  ventilating  fan. 
Whether  or  not  the  fan  is  used  with  a  hot-blast  steam  heater  is  a  question  to  be  decided  by  existing 
conditions.  The  best  arrangement  has  been  already  described,  a  heater  being  connected  to  the  outlet 
and  inlet  of  the  fan.  Where  no  provision  is  made  for  returning  the  water  of  condensation  from  the 
heaters  to  the  boiler,  the  boiler  being  on  the  same  level  so  that  gravity  return  is  impossible,  it  is 
necessary  to  resort  to  another  arrangement.  By  placing  the  heaters  in  the  bases  of  the  heating 
flues  above  the  boiler  level,  the  air  is  warmed  in  passing  over  them,  and  the  water  of  condensation  can 
be  properly  drained  from  them  without  the  use  of  a  pump  to  return  it  to  the  boiler. 

While  direct  radiation  in  the  rooms  themselves  will  provide  heat,  it  does  not  provide  a  change 
of  air,  and  hence  a  fan  must  still  be  employed  for  ventilation.  Moreover,  unless  the  fan  is  used,  an 
air  washer  cannot  be  installed  and  there  is  no  opportunity  to  cleanse  or  moisten  the  air,  as  is  the  most 
modern  practice. 

With  the  Sturtevant  System  are  obtained  the  benefits  of  heating  and  ventilation  with  the 
added  advantage  of  air-washing  apparatus  to  improve  the  quality  of  the  air.  Fan,  motor,  heater 
and  air  washer  are  all  centrally  located  where  they  are  under  the  entire  control  of  one  man.  Leaking 
steam  pipes  and  radiators  in  rooms  are  eliminated;  there  is  no  necessity  of  opening  windows  to  obtain 
fresh  air.  The  system  is  independent  of  weather  and  temperature.  It  is,  moreover,  possible  to  heat 
with  much  greater  rapidity,  a  school-house  that  has  cooled  down  over  night  or  the  week  end.

The  Importance  of  the  Air  Washer 

ONE  of  the  greatest  advances  of  recent  years  in  apparatus  for  heating  and  ventilating,  especially 
in  school-houses,  is  the  air  washer.  With  this  apparatus,  now  perfected  from  its  earlier  form 
to  a  remarkable  degree  of  practicability,  it  is  possible  to  accurately  control  the  quality  of  the  air. 

Every  one  has  noticed  how  refreshing  the  atmosphere  is  after  a  rainstorm,  how  clear  it  seems  and 
how  clean  and  wholesome  with  all  the  dust  washed  from  it.  This  is  exactly  what  the  air  washer  does. 
A  miniature  artificial  rainstorm  in  the  air  washer  cleans  from  the  air  every  particle  of  dust  and  soluble 
impurity.  Air  that  enters  the  building  through  the  windows  without  passing  through  the  air  washer 
is  dusty,  and,  besides  being  unhealthful  to  breathe,  it  soon  makes  the  furnishings  and  decorations  dingy. 
Moreover,  with  an  air  washer,  the  dry  winter  air  may  be  moistened  to  the  proper  degree  for  the  most 
healthful  conditions. 

The  Sturtevant  System,  with  its  fan,  heater  and  air  washer,  and  taking,  as  it  does,  all  the  air 
admitted  to  the  building  through  a  single  opening,  completely  controls  the  quality  and  the  condition 
of  the  air.  Where  the  only  entrance  for  air  is  through  the  doors  and  windows  of  the  building,  there 
is  no  way  of  washing,  moistening,  or  warming  the  air.  This  is  one  of  the  great  defects  in  buildings 
not  ventilated  by  the  Sturtevant  System.  With  the  Sturtevant  System  the  windows  may  be  tightly 
closed,  excluding  drafts  and  dust. 

The  Sturtevant  System,  so  universally  adopted  by  school  authorities,  is  the  best,  the  most  reliable 
and  the  most  modern.  By  the  addition  of  the  Sturtevant  air  washer,  of  which  more  is  said  in  another 
place,  the  Sturtevant  System  becomes  absolutely  complete  and  the  most  satisfactory.  It  meets  all 
laws  of  ventilation,  gives  ample  heat  in  winter,  and  can  be  used  effectively  for  cooling  in  the  hot  weather. 

In  the  concluding  pages  of  this  bulletin  will  be  found  a  partial  list  of  schools  heated  and  ventilated 
by  Sturtevant  apparatus.  This  list  represents  only  a  few  installations  in  a  single  type  of  building,  but  is 
the  best  proof  that  can  be  offered  of  the  superiority  of  Sturtevant  apparatus.

ON  the  opposite  page  will  be  found  a  plan  of  the  attic  of  the  Harvard  Dental  School  building. 
This  shows  three  Sturtevant  fans  that  are  used  for  exhausting  the  vitiated  air  from  the 
building.  They  are  placed  directly  below  the  roof  and  discharge  vertically  upward  through  it,  a  pent 
house  with  louvered  openings  covering  the  outlets  of  the  fans.  The  inlets  of  the  fans  are  connected 
to  a  system  of  vent  flues  and  ducts  through  which  the  foul  air  is  drawn. 

A  separate  system  of  blowers  in  the  basement  of  the  building  supplies  fresh  air  for  ventilating  pur- 
poses by  means  of  another  system  of  ducts. 

There  are  three  supply  fans  in  the  basement,  two  90-inch  Sturtevant  steel  plate  exhausters,  direct 
connected  to  Sturtevant  type  H  motors  having  a  maximum  speed  of  200  R.P.M.,  and  one  100-inch 
Sturtevant  steel  plate  exhauster,  direct  connected  to  a  Sturtevant  type  H  motor  having  a  maximum 
speed  of  225  R.P.M. 

In  the  roof  space  are  three  ventilating  fans,  one  80-inch  Sturtevant  steel  plate  exhauster,  direct 
connected  to  a  Sturtevant  type  H  motor  having  a  maximum  speed  of  280  R.P.M.,  one  90-inch 
Sturtevant  steel  plate  exhauster,  direct  connected  to  a  Sturtevant  type  H  motor,  250  R.P.M.  maximum

Soldan  High  School,  St.  Louis,  Mo. 


THE  Soldan  High  School  in  St.  Louis,  Mo.,  is  one  of  the  largest  and  finest  in  this  country. 
Sturtevant  apparatus  used  in  the  heating  and  ventilating  system  supplies  fresh  air  and  removes 
the  vitiated  air. 

Air  is  supplied  by  four  apparatuses,  two  Sturtevant  fans,  9  feet  in  diameter  by  4J/<?  feet  wide,  and 
two  Sturtevant  fans  9^  feet  in  diameter  by  5  feet  wide,  while  another  Sturtevant  fan  9  feet 
in  diameter  by  4  feet  wide  ventilates  the  auditorium.  The  total  air  supply  is  250,000  cubic  feet  per 
minute  for  the  entire  building,  exclusive  of  the  auditorium  which  is  supplied  with  70,000  cubic  feet 
per  minute.  A  40-inch  Sturtevant  exhauster  driven  by  a  Sturtevant  motor  ventilates  the  laboratory. 
The  heaters  for  the  first  two  apparatuses  contain  about  2000  square  feet  of  radiation  each,  while  the 
other  two  heaters  contain  about  2250  square  feet  each.  For  the  four  apparatuses  there  are  two 
tempering  coils,  each  containing  about  4270  square  feet  of  radiation.  All  heaters  are  made  up  of 
Sturtevant  heater  coils. 

Each  room  is  supplied  with  air  by  an  individual  duct  from  the  hot  and  tempered  air  room.  A 
thermostat  regulates  the  temperature  by  means  of  pneumatically  operated  dampers,  while  volume 
dampers  are  set  to  provide  eight  changes  of  air  per  hour  and  a  minimum  supply  of  30  cubic  feet  of  air 
per  hour,  per  pupil. 

Vitiated  air  leaves  the  rooms  through  individual  ducts  leading  to  the  vent  stacks.

Avondale  School 


ON  the  opposite  page  is  a  basement  plan  of  the  Avondale  school,  Cincinnati,  Ohio,  showing  a  typical 
installation  of  Sturtevant  apparatus  in  a  school-house  and  the  arrangement  of  the  heating  ducts 
and  flues. 

The  air  for  ventilation  and  heating  is  drawn  into  the  building  by  the  suction  of  the  fan  through 
a  screened  opening  in  the  basement,  and  is  warmed  by  passing  over  a  tempering  heater.  The  dust 
is  removed  by  drawing  the  air  through  an  air  washer.  Passing  through  the  fan,  the  washed  and  tem- 
pered air  is  blown  through  a  reheater  and  by-pass  under  this  heater,  into  a  divided  plenum  chamber, 
the  upper  part  of  which  contains  warm  and  the  lower  part,  the  tempered  air.  Here  automatic  regu- 
lating dampers  thoroughly  mix  the  warm  and  tempered  air  before  it  enters  the  distributing  ducts. 
These  ducts  are  of  galvanized  iron  and  are  suspended  from  the  basement  ceiling.  Vertical  flues,  con- 
cealed in  the  walls  of  the  building,  carry  the  heated  air  to  the  various  rooms. 

Air  inlet  registers  are  placed  in  the  walls  of  the  rooms  about  8  feet  from  the  floor,  while  vent 
registers  are  placed  in  the  walls  just  above  the  floor  line  and  open  into  vertical  vent  flues  which 
carry  the  foul  air  to  the  roof. 

The  fan  is  a  Sturtevant  steel  plate  exhauster,  12  feet  in  diameter  by  6  feet  wide,  and  is  driven 
by  a  direct  connected  Sturtevant  horizontal  center  crank  steam  engine.  The  tempering  coils  have 
a  total  heating  surface  of  2409  square  feet,  being  made  up  of  Sturtevant  heater  coils.  The  reheater 
contains  4818  square  feet  of  heating  surface  made  up  of  Sturtevant  heater  coils.

ON  the  opposite  page  are  shown  the  two  heating  and  ventilating  apparatuses  in  the  Engineering 
Building  of  the  University  of  Cincinnati.    These  apparatuses  consist  of  air  washers,  tempering 
coils,  fans,  engines,  and  reheating  coils. 

Air  is  drawn  from  outside  through  screened  openings,  is  heated  by  the  tempering  coils  and  then 
passing  through  the  air  washer,  the  air  enters  the  fan  and  is  blown  into  concrete  heating  ducts  which 
are  laid  beneath  the  floor  of  the  building  and  which  follow  the  contour  of  the  outside  walls  of  the 
building.  From  these  ducts  the  heated  air  is  conveyed  to  the  various  rooms  through  vertical  flues 
concealed  in  the  walls.  Vent  flues  running  to  the  roof  remove  the  vitiated  air. 

The  south  fan  is  a  Sturtevant  steel  plate  exhaust  fan  10  feet  in  diameter  by  5  feet  wide,  driven 
by  a  belt  from  a  9  by  8  Sturtevant  vertical  steam  engine,  running  at  250  R.P.M.  with  steam  at  100 
pounds  pressure.  The  fan  has  a  capacity  of  54,000  cubic  feet  of  air  per  minute  at  1 35  revolutions. 

The  north  fan  is  a  Sturtevant  steel  plate  exhauster  9  feet  in  diameter  by  5  feet  wide,  and  is 
driven  by  9  by  8  Sturtevant  vertical  steam  engine,  running  at  250  R.P.M.  with  steam  at  100  pounds 
pressure.  The  fan  has  a  capacity  of  44,000  cubic  feet  of  air  per  minute  at  1 50  revolutions.  The 
tempering  coil  used  with  the  south  fan  contains  1216  and  the  heater  1829  square  feet  of  radiation. 
Both  are  raised  to  provide  for  a  by-pass  beneath.  The  tempering  coil  of  the  north  apparatus  consists 
of  960,  and  the  heater  of  1440  square  feet  of  radiation  raised  to  provide  a  by-pass  underneath. 

The  exhaust  apparatus  consists  of  one  30-inch  and  one  24-inch  electric  propeller  fan.

THE  photograph  on  the  opposite  page  shows  the  Lincoln  School  at  Hibbing,  Minnesota,  in  course 
of  construction.     At  the  extreme  right  and  left  of  the  photograph  can  be  seen  the  galvanized 
iron  heating  flues  as  they  are  being  constructed.     These  flues  are  contained  within  the  brick  walls  of 
the  building  and  carry  the  heated  air  to  the  rooms.     The  photograph  shows  how  the  galvanized  iron 
flues  and  walls  are  erected  at  the  same  time. 

On  the  following  page  are  shown  the  two  fans  that  force  the  air  into  the  heating  ducts  and  the  steam 
engines  that  drive  the  fans.     The  heaters  are  in  a  sheet  steel  casing  behind  the  fans. 

The   fans   are   two  No.   15    Sturtevant   Multivane   exhausters,   driven   by  12  by  10  Sturtevant 
horizontal  center  crank  steam  engines.     Fans  and  engines  are  direct  connected  and  run  at  175  R.P.M. 

The  fans  have  sufficient  capacity  to  provide  the  amount  of  air  required  by  law  for  each  pupil  and 
the  necessary  frequency  of  air  change. 

The  tempering  coils  and  heaters  contain  a  total  of  9408  square  feet  of  radiation  and  are  connected 
to  the  fans  by  steel  plate  housings.

University  of  Maine 


THE   Engineering  Building  of  the  University   of    Maine   is   entirely   heated   and   ventilated   by 
Sturtevant  apparatus  which  the  University  installed  to  give  the  students  a  comprehensive  idea 
of  the  Sturtevant  hot  blast  heating  and  ventilating  system,  and  in  order  that  they  might  make  tests 
upon  it  in  connection  with  their  work. 

The  apparatus  is  situated  in  the  basement.  The  location  of  the  apparatus  and  the  plan  of  the 
heating  ducts  is  made  clear  by  the  lay-out  upon  the  opposite  page.  The  fan  is  a  Sturtevant 
steel  plate  exhauster,  6  feet  in  diameter  by  3J/2  feet  wide,  with  a  capacity  of  24,000  cubic  feet  of  air 
per  minute  and  is  belt  driven  by  a  9  HP.  Sturtevant  electric  motor  running  at  1000  R.P.M. 
The  air  necessary  for  ventilation  is  drawn  through  a  screened  opening  in  the  basement  and  is  blown 
by  the  fan  directly  through  a  heater  containing  about  1675  square  feet  of  radiation  in  one-inch 
steel  pipe  made  into  a  Sturtevant  heater.  Distributing  ducts  of  galvanized  iron  carry  the  air  to  the 
flues  and  distribute  it  to  the  various  rooms.  Inlet  registers  are  placed  in  the  walls  of  the  rooms 
about  8  feet  above  the  floor,  and  outlet  registers  are  placed  near  the  floor  connecting  with  the 
vent  flues  running  directly  to  the  roof,  where  they  discharge  the  vitiated  air  to  the  atmosphere  through 
roof  monitors.

Sturtevant  Generators 


IT  is  often  desirable  to  light  the  school  by  means  of  a  private  generating  set,  especially  in  tech- 
nical and  manual  training  schools  where  steam  boilers  are  installed.  It  being  necessary  to  main- 
tain a  janitorial  and  engineering  force,  the  cost  of  supervision  for  the  lighting  set  is  not  of  importance. 
As  the  exhaust  steam  from  the  engine  or  turbine  can  be  utilized  in  the  heating  coils,  the  cost  of 
current  is,  therefore,  very  low.  Also  the  generating  set  itself  serves  the  useful  purpose  of  practical 
illustration  to  the  students. 

Sturtevant  electric  generating  sets  are  built  with  direct  connected  steam  engine,  steam  turbine 
or  gasolene  engine  drive,  and  in  sizes  from  five  to  one  hundred  and  fifty  kilowatts,  direct  current.  All 
steam  engines,  turbines  and  generators  are  built  by  this  company  in  their  shops. 

VS-7  generating  sets  consist  of  Sturtevant  vertical  steam  engines  of  the  VS-7  type,  direct  connected 
to  Sturtevant  six  or  eight  pole  electric  generators.  These  sets  were  developed  under  the  rigid  specifi- 
cations for  the  requirements  of  the  United  States  Navy,  and  have  been  used  extensively  both  in  the 
Navy  and  wherever  high-grade  direct  connected  sets  are  required.  Because  of  this,  they  are  especially 
adapted  to  school-house  lighting,  as  they  are  reliable  and  durable  and  may  be  depended  upon  to  give 
satisfactory  service. 

HC-1  generating  sets  consist  of  Sturtevant  horizontal  center  crank  steam  engines  of  the  HC-1 
type,  direct  connected  to  Sturtevant  six  or  eight  pole  electric  generators.  These  sets  are  carefully 
balanced  and  regulated  to  give  quiet  operation  with  constant  voltage.

VS-7  Generating  Set 


Turbo  Generating  Set 


Both  HC-1  and  VS-7  generating  sets  are  automatically  regulated  by  a  Rites  centrifugal  gov- 
ernor located  in  the  fly  wheel.  The  engines  are  entirely  enclosed  with  oil  and  dust  proof  covers  and 
have  gravity  oiling  systems.  They  are  fitted  with  large  relief  valves  and  plugged  for  indicator  cocks. 
Steam  engine  generating  sets  can  be  supplied  for  low,  medium  or  high  pressure  steam. 

Sturtevant  turbo  generators  consist  of  Sturtevarit  steam  turbines  direct  connected  to  Sturtevant 
electric  generators.  The  steam  turbines  are  of  the  multi-impulse  type  with  a  single  rotor  of  solid  forged 
steel.  The  bearings  are  of  a  self-oiling  pattern,  using  a  special  channel  scoop  oiling  ring  to  insure  perfect 
lubrication.  The  sets  are  particularly  well  governed  by  a  centrifugal  governor  mounted  upon  the 
turbine  shaft.  An  entirely  separate  emergency  governor  shuts  down  the  turbine  by  means  of  an  entirely 
separate  valve  if  for  any  reason  the  speed  of  the  turbine  exceeds  a  predetermined  maximum. 

The  Sturtevant  direct  current  generators  used  with  these  turbines  are  especially  designed  for  this 
type  of  service.  The  sets  are  well  adapted  for  use  in  schools  as  they  operate  with  a  minimum  of  care 
and  attention.  They  are  well  balanced  for  vibrationless  operation  and  completely  governed  so  that  the 
voltage  is  maintained  constant  through  wide  and  sudden  vibrations  in  load. 

Sturtevant  gasolene  electric  generating  sets  consist  of  gasolene  engines  direct  connected  to 
Sturtevant  direct  current  electric  generators.  The  engines  are  of  the  four  cycle,  vertical,  multi-cylinder, 
watercooled  automobile  type,  using  either  gasolene  or  illuminating  gas  for  fuel.  It  is  intended  that 
these  sets  should  be  run  direct,  without  storage  battery,  although  this  arrangement  is  possible,  if  desired. 
The  speed  of  the  engine  is  closely  regulated  by  a  fly  ball  governor  operating  a  throttle  valve.  Lubrica- 
tion is  forced;  a  gear  pump  in  the  base  supplies  oil,  under  pressure,  to  all  bearings.  Engine  and 
generator  are  both  mounted  upon  the  same  cast  iron  base.

Sturtevant  Forges 


ALTHOUGH  they  may  not  be  classed  as  heating  and  ventilating  apparatus,  Sturtevant  forges  and 
generating  sets  are  not  out  of  place  in  this  bulletin,  as  the  complete  equipment  of  the  largest 
and  the  finest  schools  in  the  country  includes  both  forges  and  generating  sets. 

The  B.  F.  Sturtevant  Company  is  in  a  position  to  supply  forge  equipment  including  forges, 
blowers,  exhausters  and  necessary  piping  for  technical  schools  and  colleges  and  to  design  and  lay  out 
forge  shops  in  co-operation  with  architects  and  engineers. 

For  blowing  individual  forges,  the  Sturtevant  electric  forge  blower  is  economical  of  space  and 
power,  being  a  small  pressure  wheel  of  the  multivane  type  in  a  pressed  steel  casing  and  direct  connected 
to  an  electric  motor.  For  blowing  several  forges,  belt  or  electric  driven  fans  of  the  Sturtevant  steel 
plate,  or  Monogram  type  fans  are  used.  Under  these  conditions,  a  blast  pipe  leading  from  the  blower 
to  the  forges  and  generally  laid  beneath  the  floor  is  used.  For  exhausting  smoke  from  the  forges, 
a  steel  plate  or  monogram  type  of  fan  is  used  with  exhaust  pipes  leading  from  each  individual  forge. 

Type  H  forges  are  especially  designed  for  technical  and  manual  training  schools.  They  are 
constructed  of  cast  iron  for  down  or  up  draft  smoke  removal  as  desired.  Type  H-l  has  a  cast  iron 


J  C 


H-l  Forge,  without  Smoke  Cowl 


pedestal  base  open  in  front  for  ashes  and  refuse  from  the  tuyere.  Type  H  3  is  of  sheet  steel,  and  is 
fitted  with  individual  drawers  for  each  student.  Coal  and  water  tanks  are  of  cast  iron  bolted  to  the 
sides  of  the  forge  and  each  provided  with  a  tool  rack. 

Sturtevant  forges  are  equipped  with  dumping  tuyeres,  operated  from  the  front  of  the  forge  and 
have  adjustable  blast  gates. 

For  exhausting  smoke  from  the  forges,  either  the  up  or  down  draft  may  be  used.  Down  draft  forges 
have  a  special  swivelled  cowel,  adjustable  to  any  position  by  means  of  a  toothed  sector  and  worm 
operated  by  a  hand  crank.  The  exhaust  smoke  flue  extends  below  the  floor,  and  meets  the  main 
underground  exhaust  duct.  This  arrangement  is  particularly  desirable  in  schools,  as  no  overhead 
piping  is  necessary,  both  blast  and  exhaust  pipes  being  underground. 

With  up  draft  forges,  cone-shaped  hoods  are  used.  The  height  of  these  above  the  forge  is  always 
adjustable.  Galvanized  iron  piping  connected  to  the  inlet  of  the  exhaust  fan  is  used  for  smoke  removal. 

Photographs  of  Sturtevant  forges  and  forge  equipments  are  presented  here  to  illustrate  the 
manner  in  which  they  have  been  installed  in  technical  schools.

Bulletin  No.  1013 


Importance  of  Ventilation 


POSITIVE  ventilation  in  modern  public  buildings  is  essential.  Impure  air,  air  that  has  been 
breathed,  air  that  has  been  vitiated  by  organic  matter  from  the  lungs,  is  unhealthful.  Time  and 
again  experiments  and  investigations  have  proved  this  truth,  and  it  is  within  the  experience  of  every 
one  that  the  stale,  foul  air  of  a  tightly  closed,  unventilated  room  is  not  only  offensive,  but  will  cause 
headaches. 

Realizing  the  importance  of  ventilation,  the  health  departments  of  various  states  and  cities  have 
taken  up  a  study  of  conditions  and  means  for  improvement,  and  by  their  influence  and  authority,  as 
well  as  by  general  agitation  by  physicians  and  others  conversant  with  the  facts,  laws  have  been  framed 
and  enforced  establishing  the  amount  of  air  or  the  frequency  of  air  change  to  be  provided  in  buildings 
of  various  types. 

Various  systems  of  ventilation  have  been  tried,  the  earliest  relying  upon  natural  means  such  as 
windows,  ventilating  flues,  and  automatic  ventilators,  and  the  next  stages  employing  heat  to  move 
air,  but  the  mechanical  systems  in  which  a  fan  is  used  have  been  found  by  experience  to  be  the  most 
adequate  and  efficient.  The  modern  tendency  is  decidedly  away  from  a  natural  ventilation  system  and 
toward  more  effective  and  positive  fan  systems. 

To-day,  therefore,  there  are  found  but  few  public  buildings  ventilated  by  natural  means,  the  fan 
being  considered  the  only  efficient  means  for  removing  or  supplying  air  in  large  quantities.  It  has  been

McKim.  Mead  and  White,  architects 


found  that  the  fan,  being  independent  of  the  weather  conditions,  provides  ventilation  at  all  times,  and 
that  with  mechanical  ventilation  systems  it  is  always  possible  to  control  the  quality  as  well  as  the 
quantity  of  air  supplied. 

THE  STURTEVANT  SYSTEM. 

The  Sturtevant  System  is  the  blower  system  of  heating,  cooling  and  ventilation  in  its  most  per- 
fect form.  It  provides  for  a  supply  of  warm  or  cool  fresh  air  to  all  parts  of  a  building,  ventilating 
and  heating  or  cooling  the  rooms  with  the  same  air.  In  order  to  supply  fresh,  clean  air  only,  all  air 
entering  the  ventilating  system  is  washed  in  an  air  washer.  Thus  all  the  dust  and  soluble  impurities 
are  removed,  and  the  air  has  greatly  improved  breathing  qualities.  It  will  be  seen  that  such  a  sys- 
tem as  this  is  independent  of  outside  weather  conditions,  and  that  uniform,  comfortable  temperatures 
can  be  maintained  at  all  times  of  the  year;  for  with  this  system  it  is  possible  to  warm  the  air  in  winter 
and  to  cool  it  in  summer  if  proper  provision  is  made. 

FLEXIBILITY  OF  THE  SYSTEM. 

With  the  Sturtevant  System  all  air  entering  the  ventilating  system  is  drawn  through  specially 
provided  inlets  by  the  suction  of  the  fan.  In  winter  the  air  is  slightly  warmed  by  passing  over  steam 
tempering  coils,  and  is  cleansed  in  the  air  washer  through  which  it  must  pass  before  reaching  the  main 
heating  coils  placed  between  the  air  washer  and  the  inlet  of  the  fan.  In  summer  no  steam  is  used  in

Note  ventilating  registers  in  walls 


the  tempering  or  heating  coils,  but,  if  arrangements  have  been  made  to  do  so,  the  air  is  cooled  by 
refrigerating  coils  placed  in  the  air  washer  or  by  cold  brine  circulated  through  the  heater  coils.  The 
fan  blows  the  air  through  ducts  and  flues  into  the  various  rooms  of  the  building.  The  air  enters  the 
rooms  through  registers  in  the  walls  or  floor,  and  leaves  through  other  registers  which  open  into  vent 
flues.  By  means  of  the  vent  flues  the  vitiated  air  is  removed  from  the  rooms,  and  is  not  allowed  to 
remain  to  contaminate  the  fresh  air  entering.  It  is  customary,  in  large  buildings  such  as  theatres, 
to  provide  a  fan  to  exhaust  the  vitiated  air  from  the  vent  flues,  making  the  removal  of  the  vitiated 
air  absolutely  certain.  A  complete  circuit  of  air  into  and  out  of  the  building  is  provided  by  this  sys- 
tem of  heating  and  ventilation,  and  an  abundant  supply  of  fresh,  clean  air  is  assured. 


EASE  OF  TEMPERATURE  CONTROL. 

The  temperatures  of  buildings  in  which  the  Sturtevant  System  is  installed  are  easily  controlled 
automatically  by  means  of  thermostats  and  pneumatically  operated  air  dampers  or  steam  valves.  No 
regulation  need  be  left  to  the  charge  of  an  attendant  nor  to  the  occupants  of  the  rooms  themselves. 
The  uniform  temperature  maintained  throughout  the  entire  year,  both  winter  and  summer,  in  build- 
ings ventilated,  heated,  and  cooled  by  the  Sturtevant  System,  is  the  best  for  the  occupants  and  for  the 
furniture  and  woodwork,  because  the  sudden  and  extreme  variations  in  weather  conditions  which  have 
such  a  noticeable  effect  upon  the  ordinary  building  will  not  be  felt  in  one  heated  and  ventilated  by 
this  system.

ARRANGEMENT  OF  THE  SYSTEM. 

The  arrangement  of  apparatus  and  the  methods  of  introducing  air  into  a  building  are  clearly  shown 
by  the  accompanying  diagramatic  illustration.  Here  the  course  of  the  air  is  traced  through  the  screened 
in-take,  through  a  tempering  coil,  air  washer,  heater,  and  fan  into  the  ducts  and  flues,  and  finally  into 
the  room  itself.  Its  course  from  the  room  through  the  vent  register  and  into  the  vertical  vent  flue  is 
also  indicated.  As  is  readily  seen,  this  continuous  change  of  air  in  a  room,  fresh  air  being  forced  in  to 
take  the  place  of  vitiated  air,  provides  the  most  excellent  ventilation,  and,  as  all  the  air  is  introduced 
through  the  registers,  and  none  is  admitted  through  windows,  this  ventilation  is  obtained  at  all  times 
of  the  year.  On  windy  days,  when  the  dust  from  the  street  is  annoying  or  the  noises  of  the  street 
too  distracting,  the  building  ventilated  by  the  Sturtevant  System  is  provided  with  an  abundance  of 
fresh,  clean  air,  while  all  the  windows  remain  closed.  What  this  means  in  offices,  hotels,  theatres,  and 
restaurants  is  easily  appreciated.  On  murky,  dusty  days  the  air  washer  has  the  effect  of  a  refresh- 
ing rain  storm;  on  hot,  stuffy  days,  the  refrigerating  system  insures  a  cool,  invigorating  atmosphere; 
on  bleak  winter  days  the  heater  maintains  a  comfortable  temperature  without  pounding  steam  pipes 
or  sizzling  radiators. 

WHERE  THE  SYSTEM  IS  USED. 

In  this  book  will  be  found  numerous  interesting  photographs  of  buildings  in  which  Sturtevant 
apparatus  for  heating  and  ventilating  has  been  installed,  photographs  of  the  apparatus,  drawings  show-

tions; and  the  buildings  themselves,  well  known  to  almost  every  one,  and  some  of  world- wide  reputa- 
tion, are  evidence  of  the  high  esteem  in  which  Sturtevant  apparatus  is  held  by  the  most  prominent 
architects  and  engineers,  and  by  large  property  owners.  Of  the  value  of  the  Sturtevant  apparatus 
scarcely  more  is  needed  than  the  presentation  of  these  photographs.  The  list  of  installations  at  the 
end  of  the  book  gives  further  evidence  of  the  universal  acceptance  of  Sturtevant  apparatus  by  archi- 
tects and  owners  of  buildings.  This  list  is  necessarily  partial,  a  complete  list  being  so  great  that  too 
much  space  would  be  required  to  publish  it.  The  list  is,  however,  representative  of  the  class  of  build- 
ing in  which  Sturtevant  apparatus  is  installed. 

Of  the  apparatus  itself  little  can  be  said  in  a  book  of  this  character,  but  in  the  last  few  pages  short 
descriptions  and  illustrations  of  some  of  the  most  important  apparatus  are  given.  All  of  this  apparatus 
is  fully  described  and  illustrated  in  special  bulletins  and  catalogs  issued  by  this  Company,  any  of 
which  will  be  sent  on  application. 

In  the  various  types  of  buildings  illustrated  in  this  book  there  are  conditions  met  with  that  are 
peculiar  to  each  building  as  a  type.  These  conditions  are  considered  with  great  care  by  the  archi- 
tect or  engineer  who  designs  the  heating  and  ventilating  arrangements.  The  Sturtevant  System  is 
able  to  meet  all  these  conditions,  and  to  perform  its  duty  of  heating  in  all  types  of  buildings  and  with 
certain  distinctive  advantages  in  many  cases.  A  few  of  these  advantages  are  emphasized  here  with 
special  reference  to  the  buildings  in  which  they  obtain.

DISTINCTIVE  TYPES  OF  BUILDINGS. 

In  the  office  building  or  bank  the  importance  of  the  ventilation  afforded  by  the  Sturtevant  System 
is  often  overlooked.  Ventilation  has  a  vital  bearing  upon  the  health  and  personal  efficiency  of  office 
employees.  Unventilated  offices  breed  disease,  and  induce  sluggishness  and  brain  fag.  They  increase 
the  sick  list,  and  hence  the  necessary  office  force  and  pay-roll.  The  records  of  a  government  office 
building  show  that  the  sick  leave  was  reduced  45  per  cent,  when  a  change  was  made  into  a  new,  well- 
ventilated  building, — a  most  potent  argument  for  the  installation  of  a  positive  ventilation  system. 

The  theatre  particularly  demands  the  unusual  opportunity  for  ventilation  afforded  by  the  intro- 
duction of  the  Sturtevant  System,  for  in  this  type  of  building  it  is  impossible  to  ventilate  by  means  of 
windows,  and  ventilation  is  absolutely  necessary.  Heating,  while  necessary  before,  is  not  so  essential 
after  the  audience  has  assembled,  as  it  then  becomes  a  question  of  ventilating  rather  than  heating.  In 
this  type  of  building  air  is  blown  through  outlets  in  the  floor  of  the  auditorium,  one  outlet  being  pro- 
vided for  each  seat,  and  is  removed  through  grill  work  in  the  ceilings,  walls,  and  proscenium.  An 
exhaust  fan  is  used  to  aid  in  the  removal  of  the  vitiated  air.  A  constant  flow  of  air  through  the  theatre 
is  provided,  and  in  summer  the  theatre  can  be  cooled  by  using  a  refrigerating  system  in  connection 
with  the  air  washer.  A  cool,  well- ventilated  theatre  attracts  a  large  and  desirable  patronage. 

Churches  also  are  admirably  suited  to  the  Sturtevant  System.  All  direct  radiation,  except  in  small 
rooms,  is  done  away  with,  and  consequent  noise  from  pounding  steam  pipes  is  eliminated.  Moreover, 
ventilation  is  obtained,  and  both  heating  and  cooling  can  be  accomplished.  Churches  that  are  occu- 
pied only  one  day  in  seven  are  rapidly  heated  after  having  cooled  for  six  days  during  the  week.

The  perfect  regulation  of  temperature  and  the  clean,  fresh  air  obtainable  where  the  Sturtevant 
System  is  installed  is  of  particular  advantage  in  hotel  restaurants  and  cafes.  The  cool  restaurant  or 
cafe  where  the  air  is  always  fresh  and  free  from  cooking  odors  is  sought  for  by  discriminating  diners, 
rather  than  the  hot  and  stuffy  restaurants  which  are  always  foul  with  tobacco  smoke  and  cooking  odors. 
By  providing  exhaust  ventilation  the  atmosphere  may  be  kept  clean,  even  though  considerable  smoking 
is  done. 

Clubs  and  smoking-rooms  should  be  adequately  ventilated  by  exhaust  fans,  a  small  fan  often 
performing  astonishing  results  when  used  for  this  purpose.  The  local  ventilation  of  toilets,  kitchen 
ranges,  and  telephone  booths  has  been  studied  carefully  by  this  Company,  and  many  successful  instal- 
lations have  been  made  in  which  these  parts  of  the  building  are  ventilated  independently  of  all  others. 

The  ventilation  afforded  by  the  Sturtevant  System  is  particularly  appreciated  in  stores  and  shops, 
and  clean  air  supplied  from  the  air  washer  is  of  great  value  in  preventing  the  rapid  deterioration  of 
stock  exposed  for  sale.  Shoppers  soon  learn  to  remain  longer,  and  do  most  of  their  shopping  in  stores 
where  the  ventilation  is  noticeably  good,  and  where  the  atmosphere  is  neither  hot  nor  stuffy.  A  well- 
ventilated  store  has  a  more  efficient  sales  force  and  more  enthusiastic  shoppers. 

ADVANTAGES  OF  THE  STURTEVANT  SYSTEM. 

Only  one-third  to  one-fifth  as  much  heating  surface  is  required  with  the  Sturtevant  System  as  is 
necessary  with  direct  radiation  systems  because  the  heaters  are  more  efficient  when  air  is  blown  over  them, 
the  air  carrying  off  the  heat  much  more  rapidly  than  the  heat  can  radiate  without  mechanical  circulation.

The  heating  apparatus  is  entirely  centralized,  usually  in  the  basement,  and  can  be  cared  for  by 
one  attendant.  This  reduces  danger  from  fire  and  leakage,  does  away  with  radiators  in  the  rooms,  and 
eliminates  pounding  in  pipes  and  radiators. 

A  building  heated  by  the  Sturtevant  System  is  more  rapidly  warmed  after  periods  of  non- 
occupancy  than  the  building  heated  by  direct  radiation,  because  the  fan  forces  warm  air  to  every  part 
of  the  building  in  much  shorter  time  than  is  possible  by  other  means. 

The  Sturtevant  System  furnishes  ventilation  as  well  as  heating,  and  eliminates  dependence  upon 
natural  ventilation. 

The  air  washer  makes  it  possible  to  control  the  quality  of  the  air  entering  the  building  in  which 
the  Sturtevant  System  is  installed.  When  ventilation  is  not  provided  for,  the  air  must  enter  through 
windows,  admitting  dust,  cold  drafts,  dampness,  and  noise. 

An  editorial  appearing  in  the  "Heating  and  Ventilating  Magazine,"  summarized  the  advantages 
possessed  by  ventilated  buildings  as  follows: — 

"In  a  nutshell,  the  owner  or  manager  who  furnishes  his  tenants  with  offices  or  apartments  properly 
equipped  for  ventilation  and  humidity,  can  demand  and  obtain  more  rent;  his  interior  woodwork  will 
not  shrink  and  crack,  calling  for  constant  repairs;  he  can  heat  his  building  with  less  expense,  as  it  is 
a  well-known  fact  that  pure,  moist  air  takes  less  fuel  to  heat  than  does  foul,  dry  air;  he  has  a  happy, 
contented,  healthy  set  of  tenants  and,  last,  but  not  least,  is  doing  humanity  a  service."

HE  Sturtevant  System,  as  applied  to  a  combined  office  and  bank  building,  is  shown  in  the  plan 
of  the  basement  of  the  Mechanics  American  National  Bank  Building,  St.  Louis,  on  the  opposite 


page. 

This  building  is  six  stories  in  height,  the  ground  floor  being  used  for  banking  rooms,  and  the  upper 
floors  for  offices.  The  entire  six  floors  are  heated  and  ventilated  by  the  Sturtevant  System. 

The  air  entering  the  basement  is  heated  in  the  tempering  coils,  and  is  washed  in  the  air  washer. 
It  is  then  blown  into  a  small  plenum  or  air  chamber  by  a  fan  through  which  it  is  conveyed  to  the  various 
flues  by  means  of  galvanized  steel  ducts  and  flues.  The  flues  are  entirely  concealed  in  the  walls  of  the 
building. 

The  air  is  admitted  to  the  offices  through  registers  located  in  the  walls  about  eight  feet  above  the 
floor.  In  the  banking  rooms  the  registers  are  placed  in  the  floor.  The  vitiated  air  is  removed  by 
means  of  vent  flues  running  to  the  roof  and  discharging  out  of  doors. 

The  fan  is  a  No.  14  Sturtevant  multivane  exhauster,  driven  by  a  direct  connected  Sturtevant  multi- 
polar  motor. 

The  tempering  coil  contains  1,214  square  feet,  and  the  reheater  contains  2,738  square  feet  of 
radiation.

Century  Theatre,  New  York  City 

THE  ventilating  arrangements  of  the  Century  Theatre,  New  York  City,  are  shown  in  the  plan  view 
of  the  basement  on  the  opposite  page.  Direct  radiation  is  used  for  heating  the  building,  and  the 
ventilation  system  is  thorough  and  complete,  as  can  be  seen  in  the  drawing.  A  Sturtevant  fan,  motor 
driven,  forces  the  air  through  galvanized  steel  piping  moving  it  at  low  velocities  on  account  of  the 
many  turns  necessitated  by  the  arrangement  of  the  building. 

The  system  is  completely  reversible  by  means  of  a  reversing  damper  noted  on  the  drawing.  This 
is  a  particularly  desirable  feature  for  the  theatre,  as  it  is  possible  to  blow  air  into  the  auditorium  through 
the  floor  and  to  exhaust  from  it  through  the  ceiling,  or  to  reverse  the  system,  supplying  the  air  through 
the  ceiling  and  removing  it  through  the  floor. 

The  main  auditorium  floor  receives  air  from  outside  through  a  vent  shaft  running  to  the  roof  and 
located  beside  the  elevator  shaft  at  the  right  of  the  stage  pit.  As  placed  in  the  drawing,  the  reversible 
damper  opens  the  duct  which  supplies  air  to  the  auditorium  from  above,  and  permits  the  auditorium 
exhauster  to  draw  the  air  through  the  floor  outlets,  discharging  into  the  air  out-take,  a  vent  shaft 
running  to  the  roof. 

Two  short  systems  of  piping  provide  for  supplying  and  removing  all  air  from  the  corridors. 

The  stage  and  stage  boxes  are  supplied  by  separate  blowers  through  galvanized  steel  piping,  and 
all  toilets  are  ventilated  by  a  separate  system,  so  that  there  is  no  chance  of  interchange  of  air  between 
these  and  other  rooms.

The  Higbee  Store,  Cleveland,  Ohio 

THE  ground  floor  and  basement  of  the  building  of  the  Bailey  Realty  Company,  Cleveland,  Ohio, 
are  occupied  by  the  Higbee  store,  and  are  heated  and  ventilated  by  the  Sturtevant  System. 

In  the  drawing  on  the  opposite  page  will  be  found  the  basement  plan  of  this  building,  with  a  small 
elevation  view  of  the  apparatus  which  shows  the  manner  in  which  the  air  is  drawn  into  the  building, 
washed,  heated,  and  blown  into  the  ducts. 

Being  drawn  into  the  building  through  flues  from  the  roof,  the  air,  passing  through  the  tempering 
coil  and  air  washer,  is  blown  by  the  fan  through  a  heater  and  by-pass  beneath  it  into  a  double  plenum 
chamber,  the  upper  part  of  which  contains  the  hot  air  and  the  lower  part  the  tempered  air.  Rectan- 
gular galvanized  steel  heating  ducts  convey  the  air  from  this  plenum  chamber  to  the  various  outlets 
and  flues  which  supply  the  first  floor  and  the  basement. 

Mixing  dampers,  thermostatically  controlled,  regulate  the  temperature  of  the  air  entering  the  ducts 
from  the  plenum  chamber.  Air  is  removed  from  the  rooms  by  means  of  exhaust  ducts  which  are  sus- 
pended from  the  basement  ceiling.  The  vent  registers  are  placed  near  the  floor  in  the  first  story  and 
the  basement  and  communicate  with  the  ducts  through  galvanized  steel  flues. 

The  exhaust  fan  blows  air  into  a  flue  which  terminates  at  the  roof.  The  toilets  throughout  the 
building  on  all  floors  are  ventilated  by  an  80-inch  steel  plate  Sturtevant  exhauster,  driven  by  a  Sturte- 
vant direct  connected  motor. 

The  fan  supplying  air  to  the  building  is  a  7  by  4  foot  Sturtevant  steel  plate  exhauster,  driven  by  a 
Sturtevant  electric  motor.  The  tempering  coil  contains  796  square  feet,  and  the  re-heater  1,194  square 
feet  of  Sturtevant  pipe  coil  radiation. 

The  exhaust  apparatus  consists  of  a  6  by  3^/2  Sturtevant  steel  plate  fan,  driven  by  a  direct  connected 
Sturtevant  motor.  The  fan  exhausts  26,000  cubic  feet  of  air  per  minute.

Siegel's  Store,  Boston,  Mass. 

ON  the  opposite  page  is  shown  a  diagram  of  the  basement  of  Siegel's  store,  in  which  is  installed 
the  Sturtevant  System.  The  building  is  seven  stories  in  height,  and  is  heated  by  means  of  direct 
radiation  on  all  floors,  except  the  basement  and  the  first  floor. 

The  large  floor  areas  of  this  building  practically  exclude  all  possibility  of  ventilating  by  natural 
means.  For  this  reason  both  supply  and  exhaust  are  provided  for  the  first  floor  and  the  basement, 
while  the  kitchens,  toilets,  lunch  and  laundry  and  several  rooms  on  the  fifth  and  sixth  floors  are  ven- 
tilated by  means  of  an  exhaust  fan. 

As  noted  upon  the  plan,  there  are  six  boilers  provided  with  forced  draft.  The  air  used  for  the 
forced  draft  fans  is  drawn  from  the  pump  and  engine  room,  thereby  ventilating  these  places.  The 
ducts  are  shown  on  the  drawing.  A  48-inch  disc  fan  blowing  into  the  duct  leading  to  the  main  vent 
flue  ventilates  the  boiler  room. 

There  are  four  apparatuses  shown  upon  the  drawing  and  ventilating  the  first  floor  and  basements. 
Apparatus  No.  1  supplies  heated  air  to  the  seven  vestibules  on  the  first  floor.  By  heating  the  vesti- 
bules in  this  manner,  a  slight  pressure  is  maintained  within  them,  so  that  all  leakage  is  outward  from 
them,  and  there  is  no  tendency  of  the  cold  air  rushing  into  the  building  when  the  doors  are  open. 

Apparatus  No.  2  is  a  blower  heating  the  first  floor.  The  air  is  heated  by  being  passed  over  Sturte- 
vant steam  pipe  coils,  and  is  blown  through  ventilating  ducts  which  convey  it  to  the  outlet  registers. 

The  basements  and  sub-basements  are  supplied  by  Apparatus  No.  3.  The  heated  air  is  blown  into 
the  ducts  shown  in  the  drawing,  and  is  admitted  to  the  basements  through  radiators  and  diff users. 
All  the  piping  is  of  galvanized  steel,  rectangular  in  cross  section,  and  is  suspended  from  the  sub-base- 
ment ceiling.  For  exhausting  the  foul  air  from  the  basement  and  sub-basement,  Apparatus  No.  4  is 
used.  The  air  is  drawn  through  vent  registers  into  the  exhaust  ducts  by  the  fan  which  blows  it  into 
the  main  vent  flue.

Hotel  Radisson,  Minneapolis,  Minn. 

This  installation  was  made  in  an  existing  hotel,  unprovided  with  mechanical  ventilation.  Owing  to  the  small  head  room,  several 
small  Sturtevant  Multivane  fans  were  used  instead  of  a  single  large  fan.  The  illustration  shows  what  can  be  done  under  adverse  con- 
ditions to  secure  ventilation  in  existing  buildings.

PARTIAL  LIST  OF  BUILDINGS  IN  WHICH  STURTEVANT  APPARATUS  IS  INSTALLED. 

The  following  list,  necessarily  incomplete  because  a  complete  list  would  be  too  long,  is  impressive 
evidence  of  the  wide  range  of  adaptability  of  Sturtevant  apparatus  and  of  the  Sturtevant  System. 
There  are  well-known  buildings  from  all  parts  of  the  United  States  and  Canada  represented  here, — build- 
ings you  see  every  day.  When  you  are  deciding  upon  the  heating  or  ventilation  of  some  room  or 
building,  look  up  some  of  these  installations  near  you.

Equipment  for  Public  Buildings 

WE  are  always  proud  of  our  public  buildings.  We  point  them  out  to  strangers,  and,  when  we 
are  away  from  home,  we  compare  the  buildings  we  see  with  those  at  home.  We  employ  the 
best  architects  and  the  most  successful  engineers.  We  use  the  best  materials.  We  insist  upon  the 
finest  decorations  and  furnishings. 

Public  buildings  reflect  the  arts  of  the  times  in  which  they  are  built.  They  represent  the  best  that 
the  builders,  architects,  and  artists  of  the  times  have  to  offer.  The  materials  that  go  into  them  are  the 
best  that  the  builders  know,  and  the  completed  structure  remains  as  a  monument  to  the  architectural 
skill  and  the  engineering  ability  of  the  day. 

It  is  because  of  this  that  we  find  some  of  the  finest  examples  of  building  equipment  in  our  govern- 
ment, state  and  municipal  buildings,  and  that  equipment  becomes  standard  in  the  community  because 
it  has  been  chosen  in  preference  to  all  other  equipment  as  being  the  best. 

In  this  book  there  are  numerous  photographs  of  public  buildings,  including  government  and  state 
buildings,  court-houses,  libraries,  hospitals,  prisons  and  other  institutions.  All  of  these  buildings  are 
well  known,  and  many  of  them  can  be  recognized  instantly  by  people  all  over  the  world. 

All  of  these  buildings  contain  Sturtevant  apparatus  and  are  heated  and  ventilated  by  the  Sturte- 
vant  System.  Sturtevant  apparatus  was  chosen  because  of  its  superiority.  The  Sturtevant  System  was 
used  because  it  is  the  most  perfect  system  of  heating  and  ventilating  ever  devised.  A  representative 
though  incomplete  list  at  the  end  of  this  book  gives  the  names  of  other  buildings  in  which  the  Sturte- 
vant System  has  been  installed. 

THE  STURTEVANT  SYSTEM 

The  complete  installation  of  the  Sturtevant  System  provides  a  fan  or  blower,  an  airwasher,  and 
heating  coils,  while  refrigerating  apparatus  may  be  added  if  it  is  desired  to  cool  the  air  in  summer.

This  system,  complete,  meets  all  the  requirements  of  ventilation,  heats  the  building  in  winter,  cools  it  in 
summer,  and  supplies  plenty  of  pure  fresh  air,  thoroughly  cleaned,  at  all  times  of  the  year.  It  is  appli- 
cable to  buildings  of  every  type,  and  because  it  is  easily  installed  in  buildings  without  inharmonious 
architectural  effects,  it  is  especially  satisfactory  in  government,  state  and  municipal  buildings.  No 
radiators  or  steam  pipes  are  exposed  in  the  rooms  themselves,  doing  away  with  unsightliness  and  the 
distracting  noise  of  pounding  in  the  steam  pipes.  For  public  buildings  these  features  of  the  Sturtevant 
System  make  a  strong  appeal.  The  advantages  accruing  from  the  installation  of  the  System  are  many, 
and  are  summarized  on  subsequent  pages. 

The  Sturtevant  System  is  the  blower  system  of  heating  and  ventilation  in  its  most  scientifically 
developed  form.  All  the  air  used  in  the  heating  and  ventilating  system  enters  through  openings  specially 
provided  for  this  purpose.  It  is  heated  or  cooled,  as  the  case  may  be,  is  cleaned  by  passing  through 
the  airwasher  and  is  finally  blown  into  ducts  and  flues  which  carry  it  to  the  rooms  to  be  heated  or  ven- 
tilated, entering  at  such  a  reduced  velocity  that  there  are  no  drafts  as  would  result  from  windows  opened 
to  secure  ventilation.  The  quality  of  the  air  in  the  ventilating  system  is  easily  maintained  at  the  point 
of  its  greatest  excellence  because  all  of  the  air  must  pass  through  the  airwasher.  The  vitiated  air  in  the 
rooms  is  removed  through  vent  flues,  there  being,  in  most  cases,  a  fan  arranged  to  exhaust  the  air  from 
the  vent  shafts.  Registers  opening  into  the  vent  shafts  are  provided  for  removing  the  vitiated  air. 

A  complete  circuit  of  air  is  thus  established,  entering,  passing  through,  and  leaving  the  room  con- 
tinuously, bringing  with  it  fresh,  clean  air  from  outside  and  carrying  with  it,  as  it  leaves,  the  stale,  impure 
and  vitiated  air.  New  air  with  the  freshness  and  vigor  of  the  atmosphere  after  a  thunder-storm  is  being 
heated  or  cooled,  according  to  the  season  of  the  year,  for  the  supply,  and  the  stale  air  of  the  room,  already 
robbed  of  its  healthful  qualities,  is  not  heated  and  reheated  in  the  room. 

NECESSITY  OF  VENTILATION 

It  is  universally  conceded  that  artificial  ventilation  is  necessary  in  practically  all  public  buildings. 
Court-houses,  for  instance,  and  legislative  halls  require  considerable  fresh  air  because  of  the  long

periods  of  occupancy  and  the  great  number  of  people  in  the  rooms.  As  impure  air  dulls  the  mind  and 
makes  it  sluggish  in  action,  it  is  impossible  to  maintain  the  most  satisfactory  conditions  in  unventilated 
rooms.  It  is  most  strikingly  true  of  hospitals  that  ventilation  is  essential,  for  here  constitutions  that  are 
weakened  by  disease  easily  succumb  to  impure  air,  the  evil  effects  of  which  extend  farther  than  is  generally 
imagined.  This  is  emphasized  by  Prof.  Irving  Fisher,  of  Yale  University,  who  says  in  his  report  on 
"National  Hygiene":  "Man  is  more  dependent  upon  the  atmosphere  than  upon  any  other  environ- 
mental factor.  His  body  is  bathed  in  air,  and  his  most  vital  function,  respiration,  depends  upon  it." 

ADVANTAGES  OF  THE  STURTEVANT  SYSTEM 

There  is  no  class  of  buildings  to  which  this  System  is  not  adaptable  or  in  which  the  best  results 
cannot  be  obtained  by  its  introduction. 

The  entire  heating  surface  of  the  System  is  contained  in  a  single  steel  plate  jacket,  and  is  located  in 
the  basement  of  the  building,  eliminating  all  danger  from  fire  and  preventing  the  possibility  of  leakage 
with  the  attendant  damage  to  walls,  ceilings,  and  floors,  avoiding  freezing  of  isolated  radiators,  and  mak- 
ing it  unnecessary  to  place  unsightly  steam  pipes  or  radiators  within  the  rooms  themselves.  The  ob- 
jectionable though  often  unavoidable  pounding  of  radiators  is  avoided  by  locating  all  of  the  heating 
surface  at  such  a  great  distance  from  the  room  which  is  to  be  heated.  The  heating  apparatus  thus  cen- 
tralized at  one  point  is  under  the  control  of  a  single  operator. 

The  ventilation  provided  by  this  System  is  positive  at  all  times.  The  air  is  blown  by  the  fan  to 
the  rooms  where  ventilation  is  needed,  and  the  foul  air  is  exhausted  from  the  rooms  by  mechanical  means, 
no  dependence  being  placed  upon  natural  drafts  in  flues. 

The  temperature  of  the  air  entering  the  room  can  be  regulated  to  any  desired  degree,  and  the  air 
can  be  cleaned  in  the  airwasher,  removing,  thereby,  all  dirt  and  undesirable  impurities. 

The  System  supplies  both  ventilation  and  heating,  and  can  be  regulated  for  cooling  in  warm  weather. 
As  much  air  as  is  required  is  constantly  being  supplied  to  the  room,  and  the  temperature  within  the  room 
can  be  maintained  automatically  at  any  desired  degree  throughout  the  entire  year.

Cuyahoga  County  Court-house 

THE  arrangement  of  the  Cuyahoga  County  Court-house  is  such  that  the  introduction  of  the  Sturte- 
vant  System  in  it  was  accomplished  by  means  of  an  underground  concrete  duct  delivering  heated 
air  to  flues  in  the  inner  walls  of  the  building. 

The  supply  duct  is  laid  in  the  form  of  a  rectangle,  following  in  outline  the  contour  of  the  building. 
The  air  enters  through  fresh  air  inlets,  as  noted  on  the  drawing,  and  passes  through  tempering  coils, 
which  warm  it  to  a  moderate  temperature  before  it  enters  the  airwasher  just  beyond.  All  dust  and 
soluble  impurities  are  removed  from  the  air  in  passing  through  the  airwasher  on  the  way  to  the  heaters 
where  the  temperature  is  raised.  The  air  is  then  blown  by  the  fan  into  the  plenum  chamber. 

The  air  from  the  plenum  duct,  arising  in  the  flues,  is  admitted  to  the  rooms  through  registers  located 
in  the  walls  about  eight  feet  from  the  floor,  while  vitiated  air  leaves  through  vent  registers  and  flues  and 
is  removed  by  Sturtevant  steel  plate  exhausters. 

It  will  be  noticed  that  provision  is  made  for  supplying  plenty  of  warm  air  to  the  vestibules,  as  these 
parts  of  the  building  are  easily  cooled.

r  I  'HE  drawing  on  the  opposite  page  illustrates  how  the  Sturtevant  System  was  introduced  into  a  large 
1  and  complicated  building.  The  installation  of  any  system  of  heating  into  a  building  of  this  type 
is  a  difficult  matter  on  account  of  the  size  of  the  structure  and  the  number  of  rooms  to  be  heated,  and 
because  of  the  decorative  nature  of  the  interior  the  system  must  be  introduced  without  inharmonious 
effects.  The  Sturtevant  System  is  especially  adaptable  in  this  regard,  because  no  unsightly  radiators  or 
steam  coils  are  placed  in  sight,  all  being  located  in  the  basement  of  the  building.  Hammering  pipes 
and  pounding  radiators,  not  always  easily  avoidable,  are  distinctly  annoying  in  a  building  of  this  charac- 
ter. Ventilation  is  essential.  The  Sturtevant  System  provides  heat  with  the  absence  of  exposed  pipes 
and  radiators  and  also  ventilation  by  means  of  the  same  apparatus. 

There  are  several  apparatuses  used  in  heating  and  ventilating  the  New  York  Public  Library.  These 
are  shown  on  the  drawing.  The  four  main  apparatuses  are  located  at  the  left  side  of  the  central  court 
from  which  the  fresh  air  is  drawn.  A  complete  supply  and  exhaust  arrangement  for  the  stack  room  in  the 
rear  is  shown.  Apparatus  No.  5  in  the  40th  Street  end  of  the  building  exhausts  foul  air  from  the  engine 
and  pump  rooms,  and  Apparatus  No.  6  is  used  for  removing  the  fumes  from  the  storage  battery  room.

The  San  Quentm  State  Prison 

n*HERE  are  nine  Sturtevant  heating  and  ventilating  apparatuses  in  the  San  Quentin  State  Prison, 
X  four  of  which  supply  fresh  air  and  five  of  which  exhaust  the  foul  air.  These  are  located  in  two 
groups,  consisting  of  two  supply  and  two  exhaust  apparatuses  for  ventilating  the  Cell  building,  while  the 
fifth  exhauster  ventilates  the  Dining  Room  and  the  Chapel.  On  the  opposite  page,  one  of  the  groups  of 
apparatuses  ventilating  the  Cell  house  is  shown  in  outline,  and  the  ducts  which  connect  the  fans  with  the 
registers  are  indicated. 

The  supply  fans  draw  air  in  from  outside  through  heating  coils  and  force  it  into  underground  ducts, 
which  in  turn  discharge  the  air  into  the  Cell  house  through  registers  in  the  outside  walls.  The  vitiated  air 
is  removed  through  the  back  walls  of  the  cells,  these  cells  being  placed  back  to  back  and  in  tiers  with  a 
utility  corridor  between.  In  this  corridor  ventilating  flues  lead  from  the  back  of  each  cell  to  the  main 
exhaust  duct  beneath  the  floor.  The  exhaust  fans  draw  the  foul  air  through  this  duct,  and  blow  it 
outside.  On  one  of  the  following  pages  is  shown  one  of  the  supply  fans. 

Ventilation  is  essential  in  prisons,  owing  to  the  conditions  that  exist  there.  The  Sturtevant  System 
has  always  been  recognized  as  the  best  because  it  heats  as  well  as  ventilates  the  prison.  The  individual 
exhaust  from  each  cell  is  a  noteworthy  feature  of  this  System,  as  the  air  cannot  become  stagnant  in  the 
cells.

Sturtevant  Generators 


IN  the  types  of  buildings  which  are  illustrated  in  this  book  it  is  often  desirable  to  generate  electricity 
for  lighting  and  power  purposes.  On  account  of  the  size  of  these  buildings  it  is  necessary  to  main- 
tain a  large  janitorial  force,  and  the  extra  cost  of  supervision  for  the  electric  generator  is  an  item  of  no 
great  importance.  Steam  boilers  are  almost  always  installed  for  heating  purposes,  so  that,  by  the  in- 
stallation of  a  boiler  to  generate  steam  at  pressures  sufficient  for  driving  steam  engines  or  steam  turbines 
is  only  a  slight  additional  expense.  The  cost  of  the  current  is  also  considerably  lowered  by  reason  of 
the  fact  that  the  exhaust  steam  is  used  in  the  heating  system. 

Sturtevant  electric  generating  sets  are  built  with  direct  connected  steam  engine,  steam  turbine,  or 
gasoline  engine  drive,  and  in  sizes  from  five  to  one  hundred  and  fifty  kilowatts,  direct  current.  All  en- 
gines, turbines,  and  generators  are  built  by  this  Company  in  their  shops. 

VS-7  and  VS-8  generating  sets  consist  of  Sturtevant  vertical  steam  engines  of  the  VS-7  and  VS-8 
types,  direct  connected  to  Sturtevant  six  or  eight  pole  electric  generators.  These  sets  were  developed 
under  the  rigid  specifications  for  the  requirements  of  the  United  States  Navy,  and  have  been  used  ex- 
tensively both  in  the  Navy  and  wherever  high-grade  direct  connected  sets  are  required.  Because  of  this, 
they  are  especially  adapted  to  public  building  lighting,  as  they  are  reliable  and  durable  and  may  be 
depended  upon  to  give  satisfactory  service. 

HC-1  generating  sets  consist  of  Sturtevant  horizontal  center  crank  steam  engines  of  the  HC-1  type 
direct  connected  to  Sturtevant  six  or  eight  pole  electric  generators.  These  sets  are  carefully  balanced  and 
regulated  to  give  quiet  operation  with  constant  voltage. 


VS-7  Generating  Set 


Turbo  Generating  Set 


N 

M 


HC-1,  VS-7,  and  VS-8  generating  sets  are  automatically  regulated  by  a  Rites  centrifugal  governor 
located  in  the  fly  wheel.  The  engines  are  entirely  enclosed  with  oil  and  dust  proof  covers  and  have 
gravity  oiling  systems.  They  are  fitted  with  large  relief  valves  and  plugged  for  indicator  cocks.  Steam 
engine  generating  sets  can  be  supplied  for  low,  medium,  or  high  pressure  steam. 

Sturtevant  turbo  generators  consist  of  Sturtevant  steam  turbines  direct  connected  to  Sturtevant 
electric  generators.  The  steam  turbines  are  of  the  multi-impulse  type  with  a  single  rotor  of  solid  forged 
steel.  The  bearings  are  of  a  self-oiling  pattern,  using  a  special  channel-scoop  oiling  ring  to  insure  perfect 
lubrication.  The  sets  are  particularly  well  regulated  by  a  centrifugal  governor  mounted  upon  the  turbine 
shaft.  An  entirely  separate  emergency  governor  shuts  down  the  turbine  by  means  of  an  entirely  sepa- 
rate valve  if,  for  any  reason,  the  speed  of  the  turbine  exceeds  a  predetermined  maximum. 

The  Sturtevant  direct  current  generators  used  with  these  turbines  are  especially  designed  for  this 
type  of  service.  The  sets  are  well  adapted  for  use  in  schools,  as  they  operate  with  a  minimum  of  care  and 
attention.  They  are  well  balanced  for  vibrationless  operation  and  completely  governed,  so  that  the  volt- 
age is  maintained  constant  through  wide  and  sudden  variations  in  load. 

Sturtevant  gasolene  electric  generating  sets  consist  of  gasolene  engines  direct  connected  to  Sturte- 
vant direct  current  electric  generators.  The  engines  are  of  the  four  cycle,  watercooled,  automobile 
type,  with  either  four  or  six  cylinders  arranged  vertically  and  using  either  gasolene  or  illuminating  gas 
for  fuel.  It  is  intended  that  these  sets  should  be  run  direct,  without  storage  battery,  although  this 
arrangement  is  possible,  if  desired.  The  speed  of  the  engine  is  closely  regulated  by  a  fly-ball  governor 
operating  a  throttle  valve.  Lubrication  is  forced;  a  gear  pump  in  the  base  supplies  oil,  under  pressure, 
to  all  bearings.  Engine  and  generator  are  both  mounted  upon  the  same  cast  iron  base.

Sturtevant  Apparatus 


THE  success  of  any  heating  and  ventilating  installation  will  depend  upon  the  system  and  the  appa- 
ratus, for,  if  there  is  a  defect  in  either  of  them,  the  desired  results  are  not  obtained.  The  best 
apparatus  in  the  world  will  fail  if  used  with  a  poorly  designed  system,  while  the  most  perfect  system 
will  not  accomplish  its  purpose  with  poor  apparatus.  In  either  case,  dissatisfaction  is  certain,  and, 
before  conditions  can  be  corrected,  it  is  necessary  to  tear  out  and  replace  at  greater  cost  and  inconven- 
ience either  the  poor  system  or  the  faulty  apparatus. 

For  over  fifty  years  the  B.  F.  Sturtevant  Company  have  built  heating  and  ventilating  apparatus 
for  installation  in  buildings  of  every  character.  Some  of  the  systems  have  been  designed  by  ourselves, 
and  upon  others  we  have  consulted  with  architects  and  engineers.  We  have  the  largest  shops  in  the 
world  devoted  to  the  manufacture  of  air-moving  apparatus,  and  build  the  fan,  heater,  air-washer,  driving 
apparatus,  and  piping  system,  and  install  the  apparatus,  if  desired,  under  one  contract. 

We  solicit  at  all  times  inquiry  concerning  our  apparatus  and  consultation  with  engineers,  architects, 
and  owners  upon  the  application  of  our  apparatus.  Our  sales  engineers,  located  in  the  principal  cities 
of  the  world,  are  competent  to  give  engineering  advice,  while  our  specialists  in  various  branches  of  our 
business  are  always  at  your  service.  You  are  saved  the  costly  mistake  of  experimenting  with  untried 
and  inefficient  apparatus  and  systems  by  referring  your  problems  to  us. 

In  the  following  pages  will  be  found,  briefly  described  and  illustrated,  the  most  important  heating 
and  ventilating  apparatus  that  we  build.

Sturtevant  Multivane  Fans 


THE  Sturtevant  Multivane  fan  is  a  centrifugal,  cased  fan  of  unique  design,  and  is  to-day  popularly 
used  in   heating  and  ventilating  work  where  formerly  only  the  steel  plate  fan  was  available. 
The  new  design  makes  it  possible  for  this  fan  to  handle  large  volumes  of  air  at  moderate  pressure  and 
with  a  small  expenditure  of  power  and  makes  the  Sturtevant  Multivane  the  most  efficient  commercial 
fan  in  the  world. 

For  the  size  of  the  fan  casing,  the  Multivane  fan  is  capable  of  delivering  much  greater  volumes  of  air 
than  the  steel  plate  or  any  other  type  of  fan,  and  is,  therefore,  of  great  value  in  installations  where 
head  room  is  of  importance. 

The  distinguishing  features  of  the  Multivane  fan  are  the  blades, 
which,  instead  of  being  broad  and  flat  and  few  in  number,  like  the 
steel  plate  fan,  are  many  in  number, 
shallow,  and  cupped  with  spherical 
depressions  for  strength  and  to  pre- 
vent the  loss  of  efficiency  due  to  the 
slip  of  air  along  the  surfaces.  The 
blades  are  placed  close  together, 
there  being  a  great  number  rather 
than  a  few,  as  is  found  with  the 
steel  plate  fan.  It  will  be  readily  seen

large  inlet  area,  and  that  on  this  account  the  resistance  due 
to  restrictions  in  the  inlet  is  considerably  lowered.  The 
fan,  moreover,  because  of  its  design  is  capable  of  being 
operated  at  much  higher  speeds  than  the  steel  plate  fan, 
which  permits  of  direct  connection  with  the  electric  motor 
and  high-speed  engine. 

The  construction  of  the  fan  is  made  clear  in  the  accom- 
panying illustration.  The  blades  are  pressed  while  hot,  being 
made  of  refined  steel  plate,  varying  in  thickness  from  1 7  to  7 
gauge,  dependent  upon  the  size  of  the  fan  wheel.  The  blades 
are  riveted  to  the  side  plates  of  the  fan,  and  in  the  larger 
fans  there  is  a  third  annular  plate  used  to  strengthen  the 
wheel  construction.

Steel  plate  fan  wheels  are  made  with  T-shaped  steel  arms  cast  into  hubs  and  carrying  the  plates 
or  floats,  which,  together  with  the  side  plates  of  the  wheel,  are  constructed  of  steel  plate.  This  con- 
struction combines  minimum  weight  with  maximum  strength  and  durability,  and  the  fans  are  designed 
to  handle  large  volumes  of  air  at  low  pressure  with  a  small  expenditure  of  power.  The  fan  wheels  are 
keyed  to  steel  shafts  that  are  turned  and  ground  to  size  and  supported  in  Sturtevant  patent  brush  oiling, 
self-aligning  bearings.  The  bearings  are  so  constructed  that  the  oil  is  not  drawn  into  the  fan  by  its 
suction.  After  the  oil  reservoir  has  been  filled,  only  infrequent  attention  is  necessary  to  insure  proper 
operation  of  the  fan. 

The  steel  plate  fan  wheels  are  enclosed  in  steel  plate  casings,  with  either  single  or  double  inlet,  and 
can  be  made  to  discharge  in  any  direction.  They  may  be  driven  by  belt  or  chain  from  shafting,  motor, 
or  engine,  or  they  may  be  direct  connected  to  a  steam-engine  or  an  electric  motor.  The  fan  wheel  of 
a  direct  connected  exhauster  is  overhung  upon  the  driving  shaft  of  the  motor  or  engine.  A  sub-base 
of  steel  plate,  upon  which  the  motor  is  mounted,  is  frequently  used  in  the  case  of  a  direct  connected  unit. 
Steel  plate  fans  are  built  to  operate  against  static  pressures  up  to  4  inches  of  water  and  for  practically 
unlimited  volumes.

Small  Exhaust  Fans 

THERE   is   often   a   section  of  a  room,  a 
kitchen,  a  laboratory,  toilet,  or  basement, 
where  the  need  of  ventilation  is  particularly 
urgent.      For    ventilating    these   places   it   is 
generally  necessary  that  the  ventilating  appar-

atus  shall  be  independent  of  that  ventilating  the  rest  of  the 
building,  as  these  places  must  often  be  ventilated  when  the 
main  ventilating  system  is  not  in  operation.  For  such  cases 
small  exhaust  apparatus  is  principally  used,  as  it  provides  a 
ready  and  satisfactory  solution  to  the  ventilating  problem. 
The  "Ready-to-Run"  Ventilating  set,  built  in  five  small 
sizes,  is  particularly  adapted  to  many  of  these  problems, 
and  is  readily  applied  for  ventilation  where  small  size 
apparatus  is  required.  It  consists  of  a  small  multivane  fan 
in  a  pressed  steel  casing  and  driven  by  a  direct  connected 
electric  motor.  The  motor  and  the  fan  casing  are  rigidly 
fastened  together,  making  a  small,  compact,  and  self-contained 
unit  that  is  portable  and, as  its  name  implies,  "Ready  toRun."

Sturtevant  propeller  fans  are  usually  placed  in  the  walls  of 
the  building  discharging  directly  out  of  doors.  They  handle  large 
volumes  of  air  at  low  pressure,  and  are  used  for  exhausting  pur- 
poses. The  Sturtevant  electric  propeller  fan,  above  all  others, 
is  remarkable  for  its  strength,  reliability,  and  smoothness  of 
operation.  The  direct 
connected  electric  motor 
is  fastened  to  the  cast 
iron  wall  ring  by  a  cast 
iron  tripod. 

Electrically  driven

are  particularly  adapted  for  exhausting  smoke  fumes  and  gases 

from  engine-rooms,  laboratories  and  kitchens.     Where  they  are 

used  for  exhausting  fumes,  an  acid  resisting  wheel  and  casing 

may  be  employed,  if  desired.     They  are  constructed  of   cast 

iron  casings  with  steel  plate  wheels,  and  are  known  to  be  one  of 

the  best  of  the  Sturtevant  fans. 

Small  electrically  driven  exhaust  fans   are   particularly 

desirable,  as  these  fans  are  generally  placed  in  out-of-the-way

places  where  belt  drive  is  impracticable.    The  electric  drive 
gives  opportunity  for  remote  control  by  switch  and  starting  box.

Sturtevant  Engines 

THE  choice  of  a  drive  for  Sturtevant  heating  and 
ventilating  fans  depends  upon  the  conditions  that 
are  met  with  in  an  installation.  Where  steam  is  avail- 
able, a  steam-engine  of  one  of  the  types  made  by  this 
company  has  the  advantage  of  great  economy,  as  the 
exhaust  steam  from  the  engine  is  used  in  the  heater, 
making  the  cost  of  operation  practically  negligible. 
These  engines  are  built  for  direct  connection  to  fans 
where  this  form  of  drive  is  desired,  or  may  be  used 
with  a  belt  drive  from  the  pulley  to  the  fan  wheel. 
Where  fans  are  used  in  summer  for  ventilation,  the  ex- 
haust steam  cannot  be  used,  and  arrangement  is  often 
made  whereby  the  engine  may  be  substituted  by  a  direct 
connected  electric  motor. 

Sturtevant  fan  engines  are  built  in  either  vertical 
or  horizontal  types  for  high,  medium,  or  low  pressure 
steam.  They  are  especially  designed  for  driving  Sturte-

vant  fans,  and  are  of  high-grade  construction  in  every  respect.  All  reciprocating  parts  are  entirely 
enclosed  by  oil  and  dust-proof  covers  in  the  frame.  The  cylinders  are  fitted  with  large  relief  valves, 
making  accidents  from  water  in  the  cylinders  impossible.  Either  a  Rites  centrifugal  automatic  governor 
or  a  fly-ball  throttling  governor  may  be  used  with  this  engine.  Perfectly  balanced  engines  and  fans 
insure  quiet  operation.  Lubrication  is  supplied  from  an  elevated  tank  on  the  horizontal  engine  and 
from  a  reservoir  cast  into  the  frame  of  the  vertical  engine.  A  pump  located  in  the  sub-base  of  the 
vertical  engine  maintains  a  sufficient 
supply  of  oil  to  the  reservoir. 

Sturtevant  engines  are  designed 
to  give  maximum  service  with 
minimum  up-keep  cost.  The 
types  here  illustrated  are  espec- 
ially adapted  to  public  building  and 
school  work,  owing  to  the  excellence 
of  their  construction.  Where  relia- 
bility and  durability  are  factors  of 
first  importance,  these  engines  are 
especially  recommended.  The  low- 
pressure  engines  may  be  operated 
from  the  heating  boiler,  making  it 
unnecessary  to  install  a  high-pressure 
boiler.  HC-1  Engine 


Sturtevant  Electric  Motors 


IF  steam  for  driving  engines  is  not  available,  or  if  other  conditions  make  it  inadvisable  to  use  a  steam- 
engine,  the  electric  motor  is  an  excellent  substitute.     It  is  clean  and  quiet,  besides  being  easy  to 
look  after,  requiring  no  licensed  engineer  as  an  operator. 

The  motor  may  be  either  direct  connected  to  the  fan  or  connected  by  belt  or  chain.     A  controlling 

rheostat  should  be  furnished  with  the  motor,  so  that  it  may  be 
operated  at  various  speeds,  as  determined  by  necessity.  This 
rheostat  may  be  arranged  to  control  the  motor  from  a  distance, 
if  the  fan  is  situated  in  an  out-of-the-way  place.  All  Sturte- 
vant electric  motors  are  of  the  direct  current  type,  wound  for 
standard  voltages. 

Type  B  motors  are  of  the  bi-polar  type,  and  are  made  in 
small  sizes  for  driving  small  exhaust  and  propeller  fans.  They 
are  built  in  semi-enclosed  and  enclosed  types. 

Type  C  motors  are  of  the  multi-polar  type,  and  are  built 
for  operation  at  comparatively  low  speeds,  as  they  are  generally

Type  H  Electric  Motor 


exhaust  fans,  these  motors  may  be  supported  on  an  annular 
plate,  which  is  bolted  to  the  side  plates  of  the  fan.  The 
smaller  sizes  may  be  open,  semi-enclosed,  or  enclosed.  In 
the  larger  sizes  these  motors  are  of  the  pedestal  type. 

Type  H  motors  are  of  the  four-pole  type,  especially 
constructed  for  driving  either  by  belt,  chain,  or  direct  con- 
nected. They 
have  operating 
characteristics 
which  insure 
their  fulfilling 


the     exacting 

requirements  of  modern  service  with  a  minimum  of  repair 
and  attention.  They  are  made  open,  semi-enclosed,  or  en- 
closed, according  to  the  conditions  of  the  installation.

Sturtevant  Heaters 


STURTEVANT  standard  heaters  are  of  the  pipe  coil  type,  and  are  constructed  of  cast  iron  bases, 
into  which  are  screwed  the  heater  pipe  coils.  The  bases  are  made  to  contain  two  or  four  rows  of 
pipe,  and  may  be  of  various  lengths,  according  to  the  size  of  heater  required.  As  many  bases  as  are 
necessary  to  give  the  required  amount  of  heating  surface  may  be  combined  to  make  a  single  heater.  A 
sectional  header  is  cast  with  each  base,  so  that  a  single  continuous  supply  and  drip  header  is  made  when 
two  or  more  bases  are  fastened  together. 

The  one-inch  steel  pipe  used  in  Sturtevant  heaters  is  of  extra  thickness,  especially  made  for 
Sturtevant  heaters.  The  pipe  is  spaced  so  as  to  give  the  greatest  efficiency  of  heat  transmission 
from  the  steam  coil  to  the  air  passing  through  the  heater,  and  is  placed  "staggered,"  so  that  the  air 
comes  into  most  intimate  contact  with  all  of  the  heating  surface. 

The  heaters  are  enclosed  on  the  top,  side,  and  bottom  by  a  casing  of  steel  plate,  which  is  generally 
connected  to  either  the  inlet  or  the  discharge  of  the  fan,  so  that  the  air  is  drawn  through  or  blown 
through  the  heater.  Live  steam  at  either  high  or  low  pressure  may  be  used  in  Sturtevant  heaters.  If 
a  power  boiler  is  not  available  for  supplying  the  necessary  steam,  an  ordinary  heating  boiler  may  be 
used.  If  a  large  amount  of  exhaust  steam  is  available  from  some  engine  or  other  source  in  the  building, 
this  may  be  economically  used  in  the  heater  in  place  of  live  steam. 

If  the  fan  used  in  connection  with  the  heater  is  driven  by  steam-engine,  the  exhaust  steam  from  the 
engine  is  turned  into  one  section  of  the  heater  and  there  utilized.  This  section  is  separated  from 
the  others,  so  that  the  oily  exhaust  steam  is  not  mixed  with  the  clean  live  steam.  Although 
Sturtevant  heaters  are  intended  for  use  with  steam,  they  may  be  also  used  with  hot  water,  if 


Standard  Pipe  coil  Heater 


conditions  are  such  as  to  make  this 
a  more  desirable  heating  medium. 
The  mitre  type  of  heater  coil  is  then 
used,  as  this  offers  less  resistance  to 
the  flow  of  water.  With  this  type  of 
heater  a  vertical  and  horizontal  base 
are  used  with  vertical  and  horizontal 
pipes  forming  a  mitre. 

Sturtevant  heaters  are  more  effi- 
cient than  direct  radiation  heaters, 
from  three  to  five  times  as  much  steam 
being  condensed  per  square  foot  of 
heating  surface  as  in  direct 
radiation  heaters,  the  greater  effici- 
ency being  due  to  the  greater  velocity 
of  air  passing  over  the  heater.  In 
other  words,  only  from  one- third  to 
one-fifth  as  much  heating  surface  is 
required  when  Sturtevant  heaters 
are  used.  This  heating  surface  is, 
moreover,  all  contained  in  a  steel 
plate  jacket  and  under  the  entire 
control  of  one  man,  eliminating  leak- 
ing pipes  and  noisy  water  hammer. 


Sturtevant  Air-washer 


THE  STURTEVANT  air-washer  consists  of  three  essential  parts,  the  spray  chamber,  the  eliminator 
plates,  and  the  sump,  or  tank.     Within  the  galvanized  iron  spray  chamber  are  sets  of  nozzles  through 
which  the  water  is  forced  by  a  centrifugal  pump.     By  means  of  the  nozzles  the  water  is  divided  into  a  fine 
spray,  entirely  filling  the  interior  of  the  spray  chamber. 

The  air  which  is  drawn  through  the  spray  chamber  by  the  fan  must  pass  through  this  spray,  so 
that  the  dust  and  soluble  impurities  are  washed  from  it.  The  spray  falls  into  the  sump,  which  is  con- 
structed of  galvanized  iron  or  of  concrete,  and  which  entirely  encloses  the  lower  part  of  the  spray  cham- 
ber and  extends  under  the  eliminators. 


Spray  Head  Air-washer  Nozzle 

The  sump  is  made  water-tight,  and  is  connected  to  the  sewer  for  drainage.  A  centrifugal  circulating 
pump  draws  the  water  from  the  sump  through  a  strainer  and  forces  it  through  the  nozzles,  so  that  the 
water  may  be  used  over  and  over  again.  The  nozzles  are  made  of  cast  brass,  and  are  screwed  into  the 
pipes  which  carry  the  water.  These  nozzles  have  large  openings  to  prevent  clogging,  and  are  so  con- 
structed that  the  water  issuing  from  the  openings  strikes  against  a  curved  plate  forming  a  part  of  the 
nozzle  and  is  broken  into  a  fine  spray.

The  eliminators  are  placed  at  one  end  of 
the  spray  chamber,  and  remove  the  entrained 
water  from  the  air  before  it  passes  into  the 
fan.  Eliminators  consist  of  horizontal  plates 
of  galvanized  sheet  iron  arranged  across  the 
end  of  the  air-washer,  like  a  louver.  The 
plates  are  perforated,  the  lips  of  the  perfora- 
tions being  bent  downward,  so  that  the  air 
passing  across  them  is  wiped  against  their 
edges.  By  the  arrangement  of  the  plates 
and  the  perforations  in  them,  the  air  cannot 
pass  through  the  air-washer  without  striking 
against  the  edges  of  the  plates,  so  that  the 
moisture  is  removed  and  falls  into  the  sump. 

The  air- washer  is  an  essential  feature  of 
modern  heating  and  ventilating  equipment, 
and  is  installed  in  schools,  theatres,  hotels, 
public  buildings,  and  in  many  factories.  It 
removes  dust  from  the  air,  and  makes  the 
air  more  healthful  for  breathing  purposes, 
and,  being  clean,  the  interior  furnishings  and 
decorations  retain  their  fresh  and  cleanly 
appearance.  With  the  air-washer  it  is  possi- 
ble to  moisten  the  air  to  any  desired 
humidity.  In  summer  weather  the  temper- 
ature of  rooms  may  be  greatly  lowered  by 
cooling  the  air  in  an  air-washer.
